Reuse the auxiliary

REPLY VERB = the small grammar verb you reuse
(auxiliary: do / does / did / is / have / can...)

        sentence / question
                │
        find the reply verb
                │
      ┌─────────┴─────────┐
      │                   │
 already visible       not visible
      │                   │
   reuse it          add do / does / did
      │                   │
She is at home.       Leo likes tea.
Is she?               Does he?
Yes, she is.          He does, doesn't he?

Same reply verb, 3 shapes:
  Yes/No + person + reply verb
  reply verb + person?
  ..., opposite reply verb + person?

Find the auxiliary; if there is none, use do/does/did, then reuse it in the reply.

Introduction

Small replies, big grammar

English conversation often avoids repeating a whole verb phrase. Instead, a short reply carries the meaning with an auxiliary: 'Do you work here?' 'Yes, I do.' The same small-word logic builds short answers, echo responses, and question tags. These forms sound natural because they link back to what was just said. Learn to hear the auxiliary, or add do when there is none, and you can answer, react, agree, and check information quickly.

Do you work here? Yes, I do.

Short answers usually reuse the auxiliary, not the whole verb phrase.

Core logic

Find the auxiliary

The key word is the auxiliary, also called the operator. If the sentence already has be, have, do, or a modal such as can, will, or should, reuse that word. 'She is at home.' 'Is she?' 'Yes, she is.' If the main verb has no auxiliary in the simple present or simple past, use do, does, or did. 'Leo likes tea.' 'Does he?' 'He does, doesn't he?' In tags and most short replies, replace the noun with a subject pronoun: Leo becomes he, the meeting becomes it.

She is at home. Is she? Yes, she is.

With be, reuse be in echo questions and short answers.

Core pattern

Short answer pattern

Short answers answer yes/no questions with Yes or No + subject pronoun + auxiliary. Keep the same tense, person, and modality as the question. 'Are they late?' 'Yes, they are.' 'Did Sam call?' 'No, he didn't.' 'Have you finished?' 'Yes, I have.' 'Can we park here?' 'No, you can't.' A full sentence is possible when you want emphasis or clarity, but in normal conversation the short answer is lighter and more natural than repeating the whole predicate.

Negative questions and contractions

With negative questions, answer according to the real fact, not according to the negative shape of the question. 'Don't you like coffee?' 'Yes, I do' means I like coffee. 'Don't you need one?' 'No, I don't' means I don't need one. Positive short answers usually do not end with a contracted auxiliary: say 'Are you ready?' 'Yes, I am,' not 'Yes, I'm.' Negative answers can contract naturally: 'No, I'm not,' 'No, he isn't,' or 'No, he's not.'

Core pattern

Echo responses

Echo responses are not full answers; they show interest, surprise, or shared experience by echoing the auxiliary. A reaction echo sounds like a small question: 'I'm exhausted.' 'Are you?' With a negative statement, echo the negative auxiliary: 'I don't eat meat.' 'Don't you?' For agreement, use so + auxiliary + subject after a positive statement: 'I love this song.' 'So do I.' After a negative statement, use neither/nor + auxiliary + subject: 'I didn't understand.' 'Neither did I.' Informally, 'Me too' and 'Me neither' are common, but the auxiliary forms are more precise.

Core pattern

Question tags

A question tag attaches a mini-question to the end of a statement. The usual pattern is positive statement + negative tag, or negative statement + positive tag. Use the same auxiliary, or do-support if the statement has no auxiliary. 'The meeting starts at nine, doesn't it?' 'You aren't angry, are you?' The subject in the tag is normally a pronoun, not the full noun again. A falling voice often asks for confirmation; a rising voice sounds more like a real question.

Form variations

Useful tag variations

Some tags are fixed enough to learn as chunks. With I am, the normal tag is aren't I: 'I'm late, aren't I?' For suggestions with let's, use shall we in neutral or slightly formal speech: 'Let's take a break, shall we?' Imperatives often use will you, won't you, or can you depending on tone. Negative words such as nobody, never, and hardly make the statement negative in meaning, so the tag is usually positive. These are useful, but not every rare tag needs memorising at once.

Danger zone

Do not ignore the auxiliary

Two common mistakes come from ignoring the auxiliary. Do not use a universal tag such as 'isn't it' after every statement. Mistake: 'You like coffee, isn't it?' Corrected: 'You like coffee, don't you?' The verb like has no auxiliary, so the tag needs do-support. Do not answer an ordinary-verb question with the main verb alone. Mistake: 'Do you like tennis?' 'Yes, I like.' Corrected: 'Yes, I do.' If you choose a full answer, say 'Yes, I like tennis,' but the short answer still uses do.
Mistake 语法 A2 词汇 A1 Neutral

You like coffee, isn't it?

Do not use isn't it as a universal question tag. The tag must match the grammar of the statement.

Summary

One reusable skill

Short answers, echo responses, and tags all depend on the same skill: find the auxiliary and reuse it. If there is no auxiliary, use do, does, or did. Use pronouns in replies and tags, keep the real polarity clear, and avoid contracted positive auxiliaries at the end of short answers. Tags usually reverse polarity, while echo responses often keep or mirror what was just said. This one small system lets you sound responsive without repeating long sentences.
