A short answer keeps the essential parts
A question checking a fact can be answered with yes or no. An English short answer with be adds a subject and the appropriate verb form after Yes or No. The quality, place or profession is already known from the question and need not be repeated.
Yes, I am ready. is a correct full answer; Yes, I am. is a correct short answer. The short version does not make the full version wrong. Yes and No on their own are also possible in conversation; tone and situation affect how they sound. Here we practise the construction with a subject and be.
Yes, + subject + am/is/are. | No, + subject + am/is/are + not.
- 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.
Are you ready? — Yes, I am.
Are you ready? — Yes, I am.
Ready is not repeated because the question already establishes what the answer refers to.
Is the shop open? — No, it isn't.
Is the shop open? — No, it isn't.
It refers to the shop. The negative concerns whether the shop is open.
The answer’s subject determines the form of be
First decide whom or what you are talking about. Use am with I, is with he, she or it, and are with you, we or they. In the short-answer construction, the verb remains after the subject. Although Yes or No alone can be a separate conversational answer, do not drop be from Yes, I am or No, I am not.
A name or noun phrase in the question is usually replaced with an appropriate pronoun. In these exercises, use it for one thing and they for several. For people, follow the pronoun given in the situation rather than guessing from a name.
I → am; he/she/it → is; you/we/they → are
Is Ben at home? — Yes, he is.
Is Ben at home? — Yes, he is.
Ben is referred to as he here, so the answer uses is.
Are the keys on the table? — No, they aren't.
Are the keys on the table? — No, they aren't.
The keys are plural: replace the keys with they and use are.
The viewpoint changes in a dialogue
Do not mechanically copy the pronoun or form of be from the question. If someone asks you individually Are you…?, you answer about yourself with I am…. If a group is being addressed and you speak for everyone, the answer begins with we.
If the other person asks about themselves, Am I…?, you answer you are…. With Are we…?, consider who belongs to we. Someone in the group may answer we; someone outside it may answer you. Context determines the pronoun, not the question form alone.
Are you tired, Eva? — No, I'm not.
Are you tired, Eva? — No, I'm not.
Eva answers for herself: you in the question becomes I in her reply.
Are you both ready? — Yes, we are.
Are you both ready? — Yes, we are.
One of the two people confirms that both are ready, so uses we.
Am I next? — Yes, you are.
Am I next? — Yes, you are.
A staff member answers a visitor: the visitor’s I becomes you in the staff member’s reply.
Do not contract be at the end of an affirmative short answer
A short answer and a contracted word form are different things. Yes, I am. is short because it does not repeat the quality or action, but am remains in full. When an affirmative answer ends in be, do not write Yes, I’m., Yes, she’s. or Yes, they’re.
If words follow the contraction, they can form a correct full answer: Yes, I’m ready. The restriction does not apply to every sentence beginning with Yes. In an exercise requesting a short answer, a full answer may miss the learning requirement while remaining grammatically correct.
Is she busy? — Yes, she is.
Is she busy? — Yes, she is.
Busy is not repeated after is, so keep is in its full form.
Are you ready? — Yes, I'm ready.
Are you ready? — Yes, I'm ready.
This is a full answer including ready. The contraction I’m is entirely acceptable here.
Are they here? — Yes, they are.
Are they here? — Yes, they are.
At the end of an affirmative short answer, write they are, not they’re.
Negative answers have several correct forms
After No, keep the negative within the construction: No, she is not. With is and are, you can contract not: isn’t, aren’t. Alternatively, contract the pronoun with be: she’s not, we’re not. The meaning stays the same.
For I, the ordinary pattern in this lesson is No, I am not. or No, I’m not. Do not put isn’t or aren’t after I in this answer. Full negative forms are correct, and contracted ones are also natural in ordinary speech.
Is she a doctor? — No, she isn't. / No, she's not. / No, she is not.
Is she a doctor? — No, she isn't. / No, she's not. / No, she is not.
All three versions deny the same fact and agree with she.
Are you cold? — No, I'm not. / No, I am not.
Are you cold? — No, I'm not. / No, I am not.
One person answers for themselves; both forms with am are correct.
Are they new? — No, they aren't. / No, they're not.
Are they new? — No, they aren't. / No, they're not.
You can contract are not or they are. Do not apply both contractions at once.
The question establishes what you are answering
Yes confirms the fact asked about; No denies it. Is the bag heavy? and Is the bag light? ask about different qualities, so the same real bag may require different answers. Do not choose Yes merely because the situation feels positive.
This lesson uses questions with am, is and are. A familiar -ing question such as Are they coming? also allows Yes, they are. The short answer keeps be without repeating coming. This applies the same answer pattern; it is not a separate lesson on tense formation.
Where is the café? needs a location, not Yes, it is. Questions with do, can, was and other forms have their own answer patterns, which are not practised here.
Is the bag heavy? — No, it isn't. It's light.
Is the bag heavy? — No, it isn't. It's light.
The short answer denies heavy. The following full sentence explains the actual situation.
Are they coming? — Yes, they are.
Are they coming? — Yes, they are.
Coming is already in the question. The answer needs they and are.
Where is the café? — It's next to the bank.
Where is the café? — It's next to the bank.
This asks about a place. A Yes/No pattern does not supply the required information.
Add a detail when it helps the listener
A short answer can begin a longer reply. First confirm or deny the fact, then add a clarification, thanks or a new question if useful. You do not need to repeat the entire phrase from the question merely to make the reply feel complete.
Before replying, check three things: whom or what you are talking about, whether the fact is true, and which form of be matches your subject. If an affirmative short answer ends in be, leave it in full. You can invent ordinary everyday situations for practice.
Are you a student? — Yes, I am. Are you a student too?
Are you a student? — Yes, I am. Are you a student too?
The answer about yourself uses I am; the new question addressed to the other person uses Are you.
Is this your coat? — No, it isn't. Mine is blue.
Is this your coat? — No, it isn't. Mine is blue.
The short negative concerns the particular coat being shown. The clarification helps identify the right one.
Common mistakes
Incorrect:Yes, I are.
Correct:Yes, I am.
Make be agree with I in the answer, even if the question began Are you.
Incorrect:Yes, I'm.
Correct:Yes, I am.
This affirmative short answer ends in be, so I’m does not fit. With a continuation, as in I’m ready, the contraction would be correct.
Incorrect:No, she not.
Correct:No, she is not.
Not does not replace the verb. Is is needed between she and not; she isn’t and she’s not are also possible.
Incorrect:No, I isn't.
Correct:No, I'm not.
Isn’t contains is and does not agree with I. Use I am not or I’m not.
Incorrect:Yes, they is.
Correct:Yes, they are.
They requires are whether the question concerns people, objects or an action.
