Verb "to be"

A1: understand and write I’m, you’re, he’s, she’s, it’s, we’re, they’re, isn’t and aren’t. Keep the meaning and negation, distinguish it’s from its, and learn why I’m ready is possible but Yes, I’m cannot end a short answer.

Contractions of to be: the same idea in a shorter form

1. A contraction does not change the fact

I am here and I’m here say the same thing. A contraction removes some letters and marks their place with an apostrophe. It is a normal English form, especially in conversation and informal messages, rather than a separate tense.

The meaning alone does not tell you whether the written English form is contracted. First understand who is speaking and what they are stating, then look at how to be is written.

I am near the window. / I'm near the window.

I am near the window. / I'm near the window.

Both versions give the same location; I’m combines I and am.

They are our guests. / They're our guests.

They are our guests. / They're our guests.

The contraction neither changes the number of people nor adds a negative.

2. The subject first, then the right contraction

I combines with am, he/she/it with is, and you/we/they with are. Contracting the form preserves this agreement. Attach the apostrophe and ending to the pronoun without a space.

After the contraction, add the information: who someone is, what they are like or where they are. Do not add another am/is/are: in She’s ready, is is already contained in She’s.

How to build it

I am → I’m; you are → you’re; he is → he’s; she is → she’s; it is → it’s; we are → we’re; they are → they’re

You're a good listener.

You're a good listener.

We address the listener: you are becomes you’re.

She's at the café. We're at home.

She's at the café. We're at home.

She needs is, while we needs are; the short forms differ.

He's new here.

He's new here.

He’s already means he is; no additional is is needed.

3. Negatives: more than one way to contract

In he is not, she is not and it is not, you can contract the pronoun with is or is with not: he’s not / he isn’t. Likewise, we’re not / we aren’t and they’re not / they aren’t. Both ways preserve the negative.

For I am not in the standard form practised here, use I’m not. Do not transfer aren’t from you to I. Regional amn’t occurs in Irish and Scottish varieties of English, but is not the target form in this course.

With a noun subject, contracting the verb with not is useful: The chair isn’t free; The chairs aren’t free. Do not insert they before aren’t when The chairs is already the subject.

How to build it

is not → isn’t; are not → aren’t; I am not → I’m not

She's not tired. / She isn't tired.

She's not tired. / She isn't tired.

Both versions preserve she, is and negative not.

We're not hungry. / We aren't hungry.

We're not hungry. / We aren't hungry.

Contracting at different points does not create a different fact.

I'm not outside. The doors aren't open.

I'm not outside. The doors aren't open.

With I, use I’m not; combine plural doors with aren’t.

4. It’s and its: the apostrophe changes the structure

In these exercises, it’s means it is: we describe a characteristic, state or place. Its without an apostrophe expresses possession before a noun: its name, its door, its screen.

Check by substitution: if it is fits here, use it’s. If you mean a name, part or thing belonging to an object or animal already mentioned, use its. In other topics, it’s can also mean it has; we do not practise that meaning here.

It's an old phone. Its screen is clean.

It's an old phone. Its screen is clean.

First it is describes the phone; then its identifies whose screen it is.

It's a small shop. Its door is blue.

It's a small shop. Its door is blue.

It is a small shop makes sense, but it is door cannot replace its door.

5. The boundary: a short answer with no continuation

In a complete positive short answer after yes, keep full am/is/are: Yes, I am; Yes, he is; Yes, they are. Do not end such an answer with I’m, he’s or they’re.

If the sentence continues, a contraction is possible: Yes, I’m ready. A negative short answer can also use a contraction: No, I’m not; No, he isn’t; No, they’re not. The important point is the structure of the whole answer, rather than yes/no itself.

Are you ready? — Yes, I am.

Are you ready? — Yes, I am.

Am ends the positive short answer, so it is not contracted.

Are you ready? — Yes, I'm ready.

Are you ready? — Yes, I'm ready.

Ready follows I’m: this is a full statement, rather than the unacceptable standalone Yes, I’m.

Is the room cold? — No, it isn't.

Is the room cold? — No, it isn't.

Negative isn’t can end a short answer.

6. Natural in conversation, but not compulsory everywhere

Contractions suit everyday conversation, notes or messages to someone you know. A full form can also be correct in conversation, particularly for emphasis. Do not consider I am fine incorrect simply because I’m fine is possible.

The advice to use full forms in official texts is a style guideline, rather than a different grammatical meaning. Here we practise short everyday statements, rather than official letters.

For a self-check, ask: is the subject unchanged, is not preserved, is there an apostrophe, and can the sentence end here? If a task explicitly requests a contraction, a full form may be grammatical but miss that requirement. A model open answer is one possible version, rather than a list of every correct sentence.

I'm fine, thanks. / I am fine, thanks.

I'm fine, thanks. / I am fine, thanks.

Both forms are possible; the short form is usual in a relaxed reply.

They're not my bags. My bags are here.

They're not my bags. My bags are here.

You do not need to contract every verb: clearly correcting the misunderstanding matters.

Common mistakes

Incorrect:I's hungry.

Correct:I'm hungry.

I needs am, so the contraction is I’m. An apostrophe alone does not ensure agreement.

Incorrect:She's is ready.

Correct:She's ready.

She’s already includes is; the second verb is unnecessary.

Incorrect:The keys isn't here.

Correct:The keys aren't here.

Keys is plural. Contract negative are not to aren’t.

Incorrect:Its a quiet room.

Correct:It's a quiet room.

It is is required here, rather than possessive its before a noun.

Incorrect:The phone is old. It's screen is clean.

Correct:The phone is old. Its screen is clean.

The screen belongs to the phone: use its screen, rather than it is screen.

Incorrect:Are you here? — Yes, I'm.

Correct:Are you here? — Yes, I am.

Without a continuation, a positive short answer ends with full am.

Sources

Questions with am, is and are: checking rather than stating

1. One question: one fact to check

Compare the statement “The room is free” with the question “Is the room free?” In the question, you do not yet assert the fact; you leave the listener the opportunity to confirm or deny it.

This is called a yes/no question. The answer can be longer than yes or no; the name describes the kind of fact being checked. Here we practise questions about present states, possession, roles and simple locations.

The room is free.

The room is free.

This is a statement: the speaker presents the room being free as a fact.

Is the room free?

Is the room free?

The speaker checks the same fact. Is moves before the room.

Are you cold?

Are you cold?

We ask about the listener’s state, rather than the name or location of something.

2. The form of be first, then the subject

The subject answers “Who or what is this sentence about?” I needs am; he, she and it need is; you, we and they need are. Changing the order does not remove this agreement.

Move the existing form of be to the beginning. Do not leave a second copy after the subject. Use is for the name of one person, and are for two people. You takes are even when addressing one person.

How to build it

Am + I + …? / Is + he, she, it or one item + …? / Are + you, we, they or several items + …?

Am I early?

Am I early?

I keeps am, although the verb now comes first.

Is Marta your teacher?

Is Marta your teacher?

Marta names one person, so use is.

Are we ready?

Are we ready?

The speaker includes themselves in the group we, so use are.

3. Keep the person or thing’s name together

The subject can contain several words: your new phone, the two chairs. This small group stays together in a question. Be goes before the whole group, rather than inside it.

Keep the description after the subject: an adjective, a role or a simple location expression. Do not lose a/an in a profession phrase, or at, in or from in a place expression. We do not study their separate grammar here, but these words do not disappear when the word order changes.

Is your new phone expensive?

Is your new phone expensive?

Your new phone is one complete subject; expensive describes the phone.

Are the two chairs free?

Are the two chairs free?

Two chairs is plural; two stays within the subject group.

Is your sister at home?

Is your sister at home?

Move is and keep at home after your sister.

4. Do not add do to this be

In our sentences, be itself expresses a state or relationship: busy, a driver, at work. It forms a question without do/does. Do not add either do or another be.

This is not a rule for every English verb. Questions about the activity work have another structure. Learn to keep the two patterns separate.

Are you at work?

Are you at work?

We check someone’s location with are, without do.

Do you work here?

Do you work here?

This is a correct question with a different verb, work. It shows the boundary of the topic, rather than another target of this lesson.

5. Keep the person and the intended question

English needs the appropriate form of be in a question such as Are you free? Do not omit are just because the meaning seems clear. First identify who you are asking about, then build the whole question.

If you are simply transforming a supplied sentence, do not change I to you without a reason. If you are addressing the person who said “I am new”, your question needs you instead. The situation must justify this change of roles.

Are you free now?

Are you free now?

This directly addresses the listener. Now keeps the meaning of “at this moment”.

Am I in the right room?

Am I in the right room?

You are asking about yourself, so the subject is I and the form is am.

Are they your neighbours?

Are they your neighbours?

Do not replace they with you: we ask about other people while addressing the listener.

6. A neutral question and a conversational check

She is a teacher? is possible in conversation when checking what you heard or expressing surprise. It does not meet our target of forming a neutral question with be before the subject. Not every question with statement word order is ungrammatical: its purpose and situation matter.

A neutral question often has rising intonation at the end, but that is not the only possible intonation. A rising voice is a useful starting point, rather than a ban on every other melody. Written exercises do not assess pronunciation.

Check open answers against the meaning and criteria; the model is only one way to express what is required. Questions with not, question words such as where/who, past forms was/were and the system of short answers belong to related topics.

Is she a teacher?

Is she a teacher?

The usual question structure practised in this lesson.

She is a teacher?

She is a teacher?

A possible conversational check. If the task requests neutral inversion, this is not that form, but it is not automatically a grammatical error.

Common mistakes

Incorrect:Are she busy?

Correct:Is she busy?

The order is already a question, but she needs is. Correct only the form.

Incorrect:Do you are tired?

Correct:Are you tired?

The state tired is expressed with be. Do is unnecessary; are already forms the question.

Incorrect:Is your brother is a driver?

Correct:Is your brother a driver?

The moved is is not repeated after the subject. The article a remains.

Incorrect:Your is phone new?

Correct:Is your phone new?

Your phone is a complete subject. Is must come before both words.

Incorrect:Am you in this class?

Correct:Are you in this class?

Use am with I; you needs are, even for one person.

Short answers with to be: answering about the right person

1. Keep what the answer needs

When someone asks whether a person is ready, something is open, or people are somewhere, you do not have to repeat the whole description. A short answer keeps Yes or No, a pronoun, and the appropriate form of to be.

First identify the fact being checked. Yes confirms it; No denies it. Words such as ready, open, or at home are already understood from the question.

How to build it

Yes, + pronoun + am/is/are. / No, + pronoun + am/is/are + not.

pronoun
—
A word used instead of naming a person or thing: I, you, she, it, they.

Is the door open? — Yes, it is.

Is the door open? — Yes, it is.

It refers to the door; there is no need to repeat open.

Are the cups clean? — No, they aren't.

Are the cups clean? — No, they aren't.

The answer denies that the cups are clean, not that they exist; they replaces the plural the cups.

2. A change of speaker may require a change of form

Do not copy the pronoun from the question. When someone addresses you alone, you in the question becomes I in your answer. When someone asks about themselves with Am I…?, you answer them with you.

Keep the verb to be and the present tense, but make its form agree with the subject of the ANSWER rather than mechanically repeating the question: Are you…? → Yes, I am., not Yes, I are.

You can refer to one person or several. If you answer for yourself and someone else, use we. If we in the question includes both you and the person asking, we can remain in the answer too.

Are you ready, Lina? — Yes, I am.

Are you ready, Lina? — Yes, I am.

Lina answers about herself: you → I, are → am.

Am I early? — Yes, you are.

Am I early? — Yes, you are.

The answer addresses the person who asked about themselves: I → you, am → are.

Are you and Tom neighbours? — No, we aren't.

Are you and Tom neighbours? — No, we aren't.

One person answers for two: you and Tom → we.

Are we in the right room? — Yes, we are.

Are we in the right room? — Yes, we are.

Both speakers are in the same room; we includes both of them.

3. Use a full form in an affirmative short answer

At the end of a standard affirmative short answer, write and say am, is, or are separately: do not contract it with the pronoun. This applies to all persons, not just I.

Distinguish a short answer from a full statement. Yes, I'm ready. is correct because ready follows I'm. But Yes, I'm. with nothing after it is not a correct standard short answer.

Are you a student? — Yes, I am.

Are you a student? — Yes, I am.

I takes am; am ends the answer and cannot be contracted.

Is she your neighbour? — Yes, she is.

Is she your neighbour? — Yes, she is.

She agrees with is. Yes, she's. does not work here.

Are they ready? — Yes, they are.

Are they ready? — Yes, they are.

They takes are, not they're at the end of the short answer.

Are you ready? — Yes, I'm ready.

Are you ready? — Yes, I'm ready.

This is a correct full answer with a contraction, but not the pattern in which ready is omitted.

4. Negatives have several correct forms

With I, use No, I am not. or No, I'm not. In the standard English practised here, do not form I amn't or replace am with aren't.

With he, she, and it, three forms are possible: full is not, contracted isn't, or the pronoun contracted with is followed by separate not. Similarly, you, we, and they can take are not, aren't, or you're/we're/they're not.

Full and contracted negatives preserve the same basic meaning. Contractions are common in conversation; the full form is also correct and can sound more emphatic. If a task specifically asks for a full form, a contraction will not meet that requirement even if it is grammatical.

Are you tired? — No, I am not. / No, I'm not.

Are you tired? — No, I am not. / No, I'm not.

Both answers deny that the speaker is tired; not remains a separate word.

Is he at home? — No, he is not. / No, he isn't. / No, he's not.

Is he at home? — No, he is not. / No, he isn't. / No, he's not.

All three forms are correct. In he's not, not follows the contraction.

Are they busy? — No, they are not. / No, they aren't. / No, they're not.

Are they busy? — No, they are not. / No, they aren't. / No, they're not.

You can contract are not or they are, but not both combinations at once.

5. Replace the person or thing with a clear pronoun

In a short answer, we usually do not repeat the name or noun. Use it for one thing and they for several. For a person, choose the pronoun established by context; do not guess it from their profession alone.

Then match the verb form: I am; he/she/it is; you/we/they are. The grammatical gender of an object's name in another language does not determine its English pronoun: a phone is it, not he.

Is your phone here? — Yes, it is.

Is your phone here? — Yes, it is.

One object: it + is, regardless of how the word for phone is gendered in another language.

Are Nina and Eva at work? — Yes, they are.

Are Nina and Eva at work? — Yes, they are.

Two people make a plural subject: they + are.

Is your brother a cook? — No, he isn't.

Is your brother a cook? — No, he isn't.

Brother establishes he clearly; the answer denies the particular profession named in the question.

6. Correct English and the exercise goal are different things

In a real conversation, standalone Yes. or No. is possible, as is a full answer. These are not automatically grammatical errors or impolite. Here we specifically practise the pronoun + to be pattern, so the task explicitly asks you to use it.

After a short answer, you can add a useful detail in a separate sentence. There is no need to lengthen the short answer itself or repeat the entire question.

In closed tasks requiring an exact form, follow the visible requirements for a capital letter, comma, and full stop. In your own replies, the model is only one way to express the intended meaning; check your text against the content criteria.

Is this seat free? — No, it isn't. It's for Alex.

Is this seat free? — No, it isn't. It's for Alex.

The short negative answers the question; the next sentence explains why.

Are you new here? — Yes.

Are you new here? — Yes.

A natural brief conversational reply, but without I am it does not demonstrate this lesson's target pattern.

7. Limits: the answer depends on the question

Here we work with ordinary am/is/are questions about a present state, location, or identity. These answers do not introduce do or does. However, No, she doesn't. can correctly answer a different question, for example about a regular action.

Questions with where or who require information, not just Yes/No. Negative questions, tags such as isn't it?, past was/were, and other verbs are neighbouring topics, not extra traps in this A1 lesson.

Before answering, check three things: who you are speaking about, whether you confirm or deny the fact, and which form of to be your pronoun needs.

Is Eva at work? — No, she isn't.

Is Eva at work? — No, she isn't.

A question with linking is needs is in the answer, not does.

Where is Eva? — She's at home.

Where is Eva? — She's at home.

Where asks for a location. An informative answer is appropriate here, not Yes, she is.

Common mistakes

Incorrect:Are you ready? — Yes, I are.

Correct:Are you ready? — Yes, I am.

The speaker has changed: an answer about yourself uses I, and I takes am. Mechanically copying are from the question does not work.

Incorrect:Is she busy? — Yes, she's.

Correct:Is she busy? — Yes, she is.

Do not end a standard affirmative short answer with a contraction of the pronoun and to be. The full Yes, she's busy. would be correct, but it is a different type of answer.

Incorrect:Is he here? — No, he doesn't.

Correct:Is he here? — No, he isn't.

Doesn't does not match the question's verb. It can answer a question with does, but it does not deny Is he here? using the required pattern.

Incorrect:Are they open? — No, they are.

Correct:Are they open? — No, they aren't.

To give an ordinary denial of the fact that they are open, combine No with a negative form of to be; do not lose not.

Incorrect:Are you tired? — No, I isn't.

Correct:Are you tired? — No, I'm not.

I takes am, not is. Use No, I'm not. or the full No, I am not. in a short negative answer.

I am: how to talk about yourself

1. What am means and why it is needed

In English, a complete affirmative sentence needs am: I am ready. Translate the whole idea naturally as “I am ready,” not each word separately.

I refers to the person who is speaking. The same construction works for any speaker: am does not change according to gender. In the “describe yourself” pattern, this could be, for example, ready, a driver, or from Ukraine.

How to build it

I + am + description of yourself

I am ready.

I am ready.

Ready names the speaker’s state. The English sentence needs am.

I am a driver.

I am a driver.

A driver names the speaker’s role. Am connects I with this role.

2. We use am with I

In an ordinary present-tense affirmative sentence about yourself, choose am, not is, are, or the base form be. Remember the pair I am as one way to begin a thought.

Is and are are not bad words: they are needed with other subjects. In this rule, we are practicing only the speaker I. The pronoun I is always written with a capital letter.

I am busy.

I am busy.

The speaker describes their current state, so am comes after I.

I am your teacher.

I am your teacher.

Your teacher clarifies the role in relation to the listener; this does not change the form am.

3. What can come after I am

After am, there can be a role, an adjective describing a state, a phrase with from showing origin, or an age. This is one linking verb with different messages, not four different verb forms.

It is useful to learn professions as ready-made combinations: a cook, a doctor, an engineer. There is no article before an adjective such as tired. Detailed article choice is a separate topic.

I am from… tells us about origin, not necessarily about the speaker’s current location. In English, age is also expressed with be: I am 30 or I am 30 years old. Do not translate the idea of “to me” as a separate pronoun.

I am a cook.

I am a cook.

A cook is a ready-made name for a profession after the linking verb.

I am tired.

I am tired.

Tired describes a state, not a profession, so there is no a here.

I am from Poland.

I am from Poland.

From Poland explains where the speaker is from. The speaker may be saying this in another country.

I am 30 years old.

I am 30 years old.

In the English construction, the subject remains I, and the age comes after am.

4. I'm—the same meaning in a shorter form

I am can be shortened to I'm. The apostrophe marks the missing letter a. The contraction is common in conversation; the full form is also correct and may be suitable when speaking more emphatically.

I'm already contains am: you do not need to add another am. In your own complete sentences in this lesson, both forms are acceptable unless the task specifically asks you to practice one of them.

How to build it

I am → I'm

I'm hungry.

I'm hungry.

The shorter form conveys the same meaning as I am hungry. It describes the same state and is not an error.

I am happy with my new job.

I am happy with my new job.

The full form is natural. The contraction I'm happy with my new job also keeps the same meaning.

5. From individual words to a complete sentence

For a simple affirmative sentence, first name the speaker with I, then use am, and then add information about yourself. Do not begin this kind of statement with Am I: that is the word order for a question, which we will study separately.

When someone asks about you, you become I in your answer. Do not copy you from their sentence. In this lesson, we answer with complete statements, for example, I'm ready; short answers such as Yes, I am belong to a related rule.

I am new here.

I am new here.

The order I → am → new here makes this a statement, not a question.

I'm from Georgia.

I'm from Georgia.

You can answer Where are you from? this way. The speaker is now talking about themselves, so they use I.

6. Limits of the rule and using it without prompts

Before answering, decide what the listener needs: your name, role, origin, age, or state. Choose the appropriate fact and build a complete affirmative sentence. You do not need to reveal real personal information: you can speak as an invented adult character.

Am is not a word that we mechanically put after every I. For example, I work means “I work” and already has a verb. I am working is a different construction for an action in progress; we are not practicing it here. We also do not form negatives or questions here.

A correct English answer may sometimes fail to complete a specific task: naming a profession instead of a state is not a grammatical error, but it does not answer the required meaning. After writing your own text, check its meaning, form, and suitability against the model and criteria; the model is not the only acceptable wording.

I'm a student. I'm tired today.

I'm a student. I'm tired today.

The first sentence presents a role, and the second describes today’s state. The speaker chooses both facts.

I work in a shop.

I work in a shop.

This is a correct sentence with work, but it is not an example of the target description using I am. Do not add unnecessary am before work.

Common mistakes

Incorrect:I is happy.

Correct:I am happy.

In this present-tense affirmative sentence, the subject I requires am. Simply replace is; do not change the state happy.

Incorrect:I are tired.

Correct:I am tired.

Are does not agree with I in an ordinary affirmative sentence. The speaker is still tired; correct only the form of the linking verb.

Incorrect:I ready.

Correct:I am ready.

The linking verb is missing from the standard complete English sentence. The meaning “I am ready” does not justify leaving out am in English.

Incorrect:I be a student.

Correct:I am a student.

Be is the base form. In an ordinary present-tense affirmative sentence with I, the personal form am is required.

Incorrect:I'm am from Canada.

Correct:I'm from Canada.

I'm already means I am. The second am is unnecessary; you can also write I am from Canada.

Incorrect:I am 26 years.

Correct:I am 26 years old.

When years follows a number in an age statement, finish the phrase with old. The shorter form I am 26 is also correct.

Using is with he, she, it and singular subjects

1. A small word connecting two parts of an idea

Some languages can express a person's state or role without an equivalent of is. An ordinary complete English sentence needs a verb: She is busy. He is my neighbour. Here, is connects the person to their state, role or description.

Begin with two questions: who or what am I talking about, and what do I want to say about them? Put the appropriate form of be between the subject and this description. This rule practises affirmative statements about present states, not questions or negatives.

How to build it

He / She / It + is + description.

She is busy.

She is busy.

Busy names a state; is cannot simply be removed from a complete standard sentence.

He is my neighbour.

He is my neighbour.

After is, we say who this person is in relation to the speaker.

2. The choice depends on the subject, not its length

He, she and it take is. The name of one person or one thing works the same way: Maria is, my brother is, the small shop is. Several words in the subject do not mean several people or things.

An important qualification to “singular → is”: I takes am, and you takes are even when addressing one person. Two people or several things need are. They also takes are, including when it refers to one person; pronoun choice depends on context, not a person's profession.

How to build it

He / She / It / Maria / my brother / the shop + is; I + am; you / we / they + are.

The small shop is open.

The small shop is open.

The subject contains three words, but there is one shop.

The shops are open.

The shops are open.

Shops is plural. Changing the number also changes the form of be.

You are ready. She is ready.

You are ready. She is ready.

Both statements can refer to one person, but you and she require different forms.

3. What can follow is?

After is, you can name a role or thing, describe a quality or state, or give a location or origin. The initial formula with a noun or adjective is useful but not exhaustive: from Spain and at home also naturally follow is.

In profession descriptions such as a teacher, the article belongs to the noun phrase. Do not add it before an adjective alone: is tired. Articles here support the complete sentence rather than form a separate assessment topic.

Is does not mean that any following verb can be added unchanged. He works describes an action; He is tired describes a state. Constructions such as is working are studied separately.

She is a teacher.

She is a teacher.

This names a profession; a teacher is the noun phrase after is.

He is tired.

He is tired.

Tired is an adjective describing a state; there is no a before it.

Maria is from Spain.

Maria is from Spain.

From Spain gives the person's origin; the subject Maria still needs is.

It is on the desk.

It is on the desk.

When the object is already clear, it + is can state its location.

4. It: a known object or the weather

In an ordinary description of an object, it can replace the object's name when the reference is clear. Grammatical gender in another language does not determine the English pronoun: the lamp → it. Name the object first or make sure the other person can see it.

In a weather statement, it does not replace a specific thing: It is cold outside. Even if another language can express this without a subject or linking verb, the complete English sentence needs it and is. There is no need to imagine an object that feels cold.

This is not a rule that it can never concern a person: English has separate identifying constructions such as It's Anna. Here we practise simple descriptions of objects and weather, without those additional uses.

The lamp is new. It is small.

The lamp is new. It is small.

It refers to one lamp; a feminine noun in another language does not make the English object she.

It is cold outside.

It is cold outside.

It fills the subject position in the weather statement.

5. Full and contracted forms

He is, she is and it is can contract to he's, she's and it's. In these simple descriptions, the meaning stays the same. Contractions are common in conversation and informal messages; the full form is also correct. If a task explicitly requests a full or contracted form, that is a learning requirement, not a ban on the other version in English.

The apostrophe in it's matters: it's = it is in this lesson's examples, whereas its expresses possession, as in its name. Do not add another is after he's, she's or it's: the verb is already part of the contraction. In other constructions, 's can have another meaning; those uses are not assessed here.

How to build it

He is → He's; She is → She's; It is → It's.

She is here. She's here.

She is here. She's here.

These are two correct versions of the same statement, not opposite answers.

It's blue.

It's blue.

The contraction expands to It is blue; without an apostrophe, its does not perform this role.

6. From an exercise to a short message

Introduce a person or thing, then add a useful fact: who they are, what they are like or where they are. Short sentences are sufficient. When writing about one person, you do not need to repeat the name every time if he or she has a clear reference.

When checking your work, distinguish a form error, a change of meaning and an unmet task requirement. She are here contains an error; She is at home can be grammatical but does not mean that she is here; She's here is correct English but does not meet a request to write without contractions.

Short labels and conversational fragments can lack a full sentence structure, but these tasks require complete standard sentences. An open-answer model is only one option. Compare your own text with the criteria; this is self-checking, not independent confirmation of correctness.

My friend is a nurse. She is at work.

My friend is a nurse. She is at work.

The person is introduced first, making the reference of she clear in the second sentence.

The room is clean. It is ready.

The room is clean. It is ready.

Both sentences describe the same thing; it maintains the connection between them.

Common mistakes

Incorrect:He are tall.

Correct:He is tall.

He needs is; the correction changes only the form of be, not the height or the person.

Incorrect:She am a doctor.

Correct:She is a doctor.

Am goes with I. She needs is, even when the speaker refers to just one person.

Incorrect:The door open.

Correct:The door is open.

The complete standard sentence about the state of the door lacks a linking verb. Do not transfer a pattern without a linking verb from another language.

Incorrect:My new bag are heavy.

Correct:My new bag is heavy.

The three words my new bag name one bag. Count the things, not the words in the subject.

Incorrect:Is cold outside.

Correct:It is cold outside.

A complete weather statement needs the subject it, even if another language does not use one.

Incorrect:She's is ready.

Correct:She's ready.

She's already includes is. The second is is unnecessary; the equivalent full version is She is ready.

Incorrect:Its clean.

Correct:It's clean.

To describe the object as clean, use it and is. Its without an apostrophe expresses possession and cannot replace it is.

Are: you, we, they, and several people or things

The linking verb in a complete sentence

A complete affirmative English sentence about a present state needs a form of be: We are here; They are colleagues. Do not leave out the linking verb between the subject and its location or description.

Are links the subject—the person or thing we are talking about—to a description, a role, or a place. It is not an unnecessary word or a separate action. First identify the subject, then use the appropriate form of be.

How to build it

you / we / they + are + description, role, or place

We are outside.

We are outside.

This tells us the location of a group that includes the speaker; English needs the linking verb are.

They are neighbours.

They are neighbours.

Are links they to a word describing the relationship between people; it does not name an action.

You: addressing one person or several people

You can address one person, address one person politely, or address a group. In every case, the form is you are. Do not replace are with is simply because you are speaking to one person.

The situation tells us how many people are being addressed. You are ready does not itself tell us how many people the speaker is talking to. A noun after are may help: a guest refers to one guest, while guests refers to several; the verb with you stays the same.

You are our guest.

You are our guest.

There is one person being addressed, but you still takes are; our guest remains singular.

You are our guests.

You are our guests.

Several people are being addressed: the noun guests is plural, while you are stays the same.

You are helpful.

You are helpful.

Helpful describes a quality of a person or people. Without context, we do not know how many people are being addressed.

We or they: does the group include the speaker?

We refers to the speaker together with other people. They, in our main exercises, refers to other people or things already mentioned. Both take are, but changing the pronoun changes the participants in the message.

When replying to someone, choose the pronoun from your own perspective. If the other person says you and Lina, and you reply about yourself and Lina, use we. Sharing the form are does not make we and they interchangeable.

We are in the same class.

We are in the same class.

The speaker is also a member of this class; replacing we with they would remove the speaker from the message.

The bags are here. They are heavy.

The bags are here. They are heavy.

They refers back to the bags already mentioned; the pronoun can refer to things as well as people.

A plural subject need not be a pronoun

Are also follows clearly plural nouns: the chairs, two rooms, my parents. Two separate participants joined by and also make a plural subject: Lena and Tom are here.

Look at the whole subject, not just the word nearest the verb. In Mina and I, the subject consists of two people, so it needs are, even though I on its own takes am. An ordinary singular subject follows a different rule: The door is open, but The doors are open.

A role named after are does not determine the verb form. We are a small group is correct: the subject is we, and a small group describes the group as a whole.

How to build it

plural noun / two separate participants joined by and + are + the rest of the message

noun
—
A word naming a person, thing or idea: student, book, happiness.

Two rooms are empty.

Two rooms are empty.

The subject two rooms is plural; rooms, not empty, determines the agreement.

Mina and I are busy.

Mina and I are busy.

The whole subject refers to two people; do not extend the am used with I alone to the whole group.

We are a small group.

We are a small group.

Are agrees with we, despite a small group coming after the verb.

Full forms and contractions convey the same meaning

You are, we are, and they are can be contracted to you're, we're, and they're. In an ordinary statement, they convey the same meaning; contractions are particularly common in conversation and informal writing. The full form is also correct.

In a contraction, the apostrophe marks an omitted letter: we're, not were. If an exercise specifically asks for a full form or a contraction, follow that instruction. The other grammatically correct form then fails to meet the particular task requirement; it does not become ungrammatical.

How to build it

you are → you're; we are → we're; they are → they're

We are on the right floor. / We're on the right floor.

We are on the right floor. / We're on the right floor.

Both forms state the same fact; the contraction changes neither the participants nor the time.

They're our friends.

They're our friends.

They're contains both the subject they and the form are; do not add another are.

The limits of this step and using it in conversation

Here we practise affirmative statements about a present state, role, location, or origin. Negatives, question formation, short answers, and -ing verbs are separate topics for later. You can answer a ready-made question with a full affirmative statement without studying the structure of the question itself yet.

Are is not a rule for every situation involving several people. For example, more complex cases with collective nouns are studied separately. They can also refer to one person; it still takes are. Our main situations with they explicitly involve several people or things so that you can first practise a straightforward pattern.

Before speaking, check three things: who you are talking about, whether the message needs be, and whether you have preserved the meaning. Changing We are here to They are here is grammatically possible, but it refers to different participants.

You and Eva are in room six. — We are in room six.

You and Eva are in room six. — We are in room six.

One of the people being addressed repeats the fact from their own perspective; you and Eva becomes we, while are stays the same.

The tickets are in my bag.

The tickets are in my bag.

A brief practical message: the plural subject tickets, the linking verb are, and a location.

Common mistakes

Incorrect:You is early.

Correct:You are early.

You takes are even when addressing one person. Change only the verb form.

Incorrect:We near the café.

Correct:We are near the café.

A complete English affirmative statement about a location needs a linking verb; do not leave it out between we and near the café.

Incorrect:The windows is open.

Correct:The windows are open.

Windows is a plural subject. The description open stays the same; correct only the agreement.

Incorrect:Sara and I am ready.

Correct:Sara and I are ready.

The verb agrees with the whole subject Sara and I, not with the final pronoun I.

Incorrect:They am our neighbours.

Correct:They are our neighbours.

Am goes with I; use are with they in a present affirmative statement.

Incorrect:We're are upstairs.

Correct:We're upstairs.

We're already contains are, so a second linking verb is unnecessary. We are upstairs is also a correct full version.

Am not, is not, are not: making a present fact negative

1. Negate precisely the fact that is named

A negative with be removes one characteristic, role or location from the description. It does not automatically tell us the opposite characteristic or the person’s actual location.

A complete English sentence needs be: I am not busy. Not alone is insufficient; keep the form am even when the meaning already seems clear.

The room is not cold.

The room is not cold.

We know only that it is not cold. Without more facts, we cannot claim it is very hot.

I am not busy.

I am not busy.

The speaker negates their present state; the sentence keeps am as its linking verb.

2. The subject first, then the correct be

Use am with I; is with he, she and it; are with you, we and they. Not does not change this choice. You takes are for both one listener and several.

A name or noun naming one object usually needs is. Several people or things need are: Anna is not…, Anna and Max are not….

How to build it

I am not… · he/she/it is not… · you/we/they are not…

You are not late.

You are not late.

Even when addressing one person, you needs are. The English sentence evaluates the current situation, rather than practising the past.

The bag is not heavy.

The bag is not heavy.

One bag is singular, so use is not.

Anna and Max are not neighbours.

Anna and Max are not neighbours.

Two names with and form a plural subject: are not.

3. The position of not, and the unchanged rest of the sentence

In an ordinary full negative statement, not follows am, is or are. To make a statement negative, do not move be before the subject or add do/does.

The negative itself does not remove an article, adjective or place: a teacher remains a teacher, at home remains at home. The assertion about the fact changes, rather than the sentence’s vocabulary.

How to build it

Subject + am/is/are + not + characteristic / role / place

subject / S
—
The grammatical subject: who or what the clause is about; the verb agrees with it. In The book was written, the book is the subject, although someone else does the action.

He is a teacher. → He is not a teacher.

He is a teacher. → He is not a teacher.

Add not after is; a teacher stays unchanged.

We are not at home.

We are not at home.

Not negates being at home. The place follows are not, and no auxiliary do is needed.

4. A contraction does not change the negative

Is not can contract to isn’t, and are not to aren’t. The pronoun and be can also contract: she is not → she’s not, we are not → we’re not. Both ways are usual; do not consider one incorrect solely because it looks different.

For the first person in neutral learner English, use I am not or I’m not. Do not combine two contractions in one word such as she’sn’t. If an exercise does not require a particular spelling, the full form and ordinary contraction are equally appropriate.

She is not ready. / She isn't ready. / She's not ready.

She is not ready. / She isn't ready. / She's not ready.

All three forms preserve the person, state and negative; the contraction choice adds no new fact.

We are not tired. / We aren't tired. / We're not tired.

We are not tired. / We aren't tired. / We're not tired.

You can contract are not or we are; the meaning stays the same.

I am not afraid. / I'm not afraid.

I am not afraid. / I'm not afraid.

In the short neutral form, I am contracts, while not stays separate.

5. A statement that helps the listener

A negative often corrects an assumption: the listener has misunderstood a person, object or place. You can add a true fact in a second sentence, but do not invent it when it is unknown.

Short words such as Sorry or Thank you suit a polite answer. Politeness does not require removing not or reversing the fact.

I'm not the teacher. I'm a visitor.

I'm not the teacher. I'm a visitor.

The first sentence corrects the role; the second explains it. Distinguish the speaker from the listener.

I'm not cold, thank you.

I'm not cold, thank you.

This can answer an offer of warm clothes: it names the speaker’s state and keeps a polite tone.

The keys aren't on the desk.

The keys aren't on the desk.

This is useful clarification during a search. It does not mean the speaker knows exactly where the keys are.

6. The rule’s limits and accurate qualifications

Here we practise present statements with be: states, roles and places. A place can follow be + not, rather than just a role or characteristic: here, at home, in the office. Such a statement is also a complete sentence.

Saying “amn’t does not exist” is too categorical: dictionaries record it mainly in Scotland and Ireland. Our target is neutral I am not / I’m not. The regional form is outside this learning objective, rather than evidence that no such word exists.

Don’t be late is a grammatical request or command, rather than a double negative. It instructs someone not to arrive late, rather than stating You aren’t late. Questions, short answers without a named state, commands, was/were and negatives with other verbs are studied separately.

You aren't late. / Don't be late.

You aren't late. / Don't be late.

The first is a statement about the current situation; the second is an instruction. Both are grammatical, but serve different purposes.

She is not here.

She is not here.

Here names the place; no noun or adjective needs adding to make the negative complete.

Common mistakes

Incorrect:I not busy.

Correct:I am not busy.

This English construction needs am before not; keep the linking verb in the sentence.

Incorrect:She not is ready.

Correct:She is not ready.

In a negative statement, not follows is, rather than coming between she and is.

Incorrect:The bags is not heavy.

Correct:The bags are not heavy.

Bags is plural. Negation does not remove the subject’s agreement with are.

Incorrect:I are not a driver.

Correct:I am not a driver.

I needs am; not and a driver stay in place.

Incorrect:We don't are tired.

Correct:We are not tired.

Be is already the verb in this statement. Remove unnecessary do and put not after are.

Incorrect:She'sn't at home.

Correct:She isn't at home.

Do not combine she’s and n’t. Another correct minimal option is She’s not at home.
