1. The subject: who or what we are saying something about
In the sentence She works here, the word she is the subject: we then say where this person works. A pronoun lets us avoid repeating a name or noun when the listener already understands who or what we mean.
The subject is a grammatical role, not necessarily the person or thing performing an action. In I am tired, there is no action that I am “doing”: the sentence describes my state. In an ordinary complete statement in English, a subject is needed for both an action and a state.
I am tired.
I am tired.
I refers to the speaker whose state we are describing. An action is not required for a subject.
This is my bag. It is heavy.
This is my bag. It is heavy.
It refers back to the bag already mentioned; the second sentence tells us about its property.
2. I, you, we: identify the speaker first
I is the person who is speaking or writing now. You is the addressee: one person or several people. English uses one pronoun, you, for both meanings.
We includes the speaker and someone else. It can mean “you and I” or “I and other people, but not you.” When the speaker changes, the same person can become I instead of you; the same group can become you instead of we.
You are in room five.
You are in room five. / You are in room five.
We determine how many addressees you refers to from the conversation, not from the form of the pronoun.
We live together.
We live together.
The person saying this is part of the group mentioned.
A: I am new here. B: You are welcome here.
A: I am new here. B: You are welcome here.
I in speaker A’s line and you in speaker B’s line refer to the same person—A.
3. He, she, it, they: for an already understood topic
We use he and she for a person according to that person’s known pronouns. A name or profession alone is not a reliable basis for choosing between them. In a learning situation, the necessary context will be provided.
For one thing, we usually use it. For several things, animals, or people, we use they.
They can also refer to one person when that person’s gender is unknown or unimportant, or when they is that person’s pronoun. With singular they, we say they are, not they is. This is not wrong merely because the person is one person.
Mira uses she/her pronouns. She works here.
Mira uses she/her pronouns. She works here.
The choice of she is based on the person’s explicitly stated pronouns, not on a guess based on the name.
My phone is old. It works well.
My phone is old. It works well.
English uses it for the phone.
The shops are small. They are open.
The shops are small. They are open.
They can replace the names of several things or places, not only people.
A new guest is here. They are at the door.
A new guest is here. They are at the door.
Nothing is said about the guest’s gender. They lets us continue without making that assumption.
4. Where the pronoun goes and why I is always capitalized
In an ordinary declarative sentence, the subject pronoun comes before the verb or verb phrase: We are ready; They can help. In questions, the order may be different: Are you ready? You is still the subject after are.
The pronoun I is always written with a capital letter, even inside a sentence. The other pronouns do not need a capital letter merely because they are pronouns: I know you. At the beginning of a sentence, any first word needs a capital letter.
Ordinary statement: subject pronoun + verb / verb phrase + the rest of the sentence
- 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.
- verb / V —
- A word for an action or state, such as work or be. The pattern determines its form.
- pronoun —
- A word used instead of naming a person or thing: I, you, she, it, they.
Today I work at home.
Today I work at home.
I is not at the beginning, but it is still written with a capital letter.
Are you ready?
Are you ready?
In this question, are comes before the subject you. The formula for statements is not the universal word order for all sentences.
5. He or him: the form depends on the role
For the subject of a separate complete sentence, we use I, you, he, she, it, we, they. We do not substitute me, him, her, us, or them: She calls, not Her calls.
Object forms are not “bad pronouns”: I call her is correct, but her is not the subject here. In a short informal reply, Me, or in the phrase It’s me, me should not be mechanically corrected to I. Here we are mainly practising complete sentences with an explicit subject.
She calls me.
She calls me.
She is the subject; me shows who receives the call. The roles are different, so the forms are different.
They know us.
They know us.
They is the subject. Do not correct us to we after know.
6. A pronoun should help understanding, not make the listener guess
First name the person or thing if the other person does not yet know what you mean. Then replace the repetition with a pronoun. If several possible people or things have just been mentioned and the reference is unclear, repeating the name or noun is perfectly normal.
An ordinary complete statement should not be built with the subject omitted, as in “Live nearby.” However, commands such as Come in! usually do not have an explicit subject; that is a different construction. It in It is raining or It is late can fill the subject position without referring to a specific named thing. Detailed cases involving weather, time, and distance belong to a separate topic.
When writing your own text, check three things: who is speaking, who each pronoun refers to, and whether the complete sentence has the correct subject form. The open-ended exercises below include models and self-check criteria; your answer does not have to match the model.
My neighbours have two bikes. They use the bikes every day.
My neighbours have two bikes. They use the bikes every day.
Here they refers to the neighbours, based on the meaning of use. Repeating bikes makes the second reference clear.
It is raining.
It is raining.
It does not name a person or thing making the rain; here it is a formal subject. For now, it is enough to recognize this pattern rather than study the entire separate topic.
Common mistakes
Incorrect:Him is at home.
Correct:He is at home.
In a complete sentence about a person with the pronouns he/him, the subject must have the form he. Him is needed in a different grammatical role.
Incorrect:Her likes tea.
Correct:She likes tea.
The subject she is needed here, not the object form her. The meaning “She likes tea” is clear; the error is specifically in the English form.
Incorrect:Them are ready.
Correct:They are ready.
Them cannot be the standalone subject of this standard complete sentence. The minimal correction is They.
Incorrect:Today i am busy.
Correct:Today I am busy.
This is a spelling error: I is written with a capital letter regardless of its position.
Incorrect:Am at the station.
Correct:I am at the station.
For a neutral complete statement, restore I: “I am at the station.” Informal message fragments may omit words, but that is not the goal of this exercise.
Incorrect:My phone is new. He is small.
Correct:My phone is new. It is small.
In this ordinary description, the second sentence refers to the phone, not a person or a personified character. The English choice of it does not depend on the grammatical gender of the word “phone” in another language.
