You have probably said "It's cold today, isn't it?" or "You haven't finished yet, have you?" a hundred times without thinking about it — and then frozen completely the one time someone asked you to explain the rule. That little two- or three-word question stuck onto the end of a sentence is called a question tag (also called a tag question), and it is one of the most common features of natural spoken English. Native speakers use it constantly — to check a fact, invite agreement, keep a conversation going, or even to sound polite instead of blunt. This guide breaks the whole system down into simple, repeatable steps, with dozens of examples, so that by the end you build every tag correctly without stopping to think.

What Exactly Is a Question Tag?

A question tag is a short question glued onto the end of a statement with a comma. The pattern is always the same:

[Statement], [helping verb] [+ not] [subject pronoun]?

• You like coffee, don't you?
• They aren't coming tonight, are they?
• He can swim, can't he?
• The train has left, hasn't it?
• We should leave now, shouldn't we?

Notice something in every example: the tag never repeats a full noun. "Priya is late, isn't Priya?" is not how it works — the subject in the tag is always replaced with a pronoun (isn't she?). Keep that in mind; we'll come back to it in the pronoun-reference table below.

The Golden Rule

Everything about question tags comes down to one rule, and once it is automatic, 90% of the work is done:

See it applied across several different tenses and subjects:

• She is a doctor, isn't she?
• She isn't a doctor, is she?
• You were at the party, weren't you?
• You weren't at the party, were you?
• He has finished, hasn't he?
• He hasn't finished, has he?
• They will call us, won't they?
• They won't call us, will they?

Two statements almost never mix polarity: a positive statement with a positive tag, or a negative statement with a negative tag, would sound broken in normal use — "She is a doctor, is she?" is not a standard tag question (there is one special exception for this, which you'll see in the "same polarity" section further down).

Building a Tag in 4 Steps

Instead of memorizing hundreds of sentences, learn this four-step process and apply it to anything.

• Step 1 — Find the helping (auxiliary) verb. Look at the statement: is there already an am / is / are / was / were / have / has / had or a modal like can / will / should? That word is your building block.
• Step 2 — No helping verb? Add do / does / did. Simple present and simple past sentences with an ordinary main verb (work, like, play, eat) don't have a visible auxiliary, so you borrow one: do (present, plural/you/I), does (present, he/she/it), or did (past, any subject).
• Step 3 — Flip the polarity. Positive statement → make the tag negative by adding n't. Negative statement → drop the not and keep the tag positive.
• Step 4 — Swap the subject for a pronoun. A name or noun in the statement becomes he, she, it, they, we, or you in the tag.

7 Special Cases to Memorize

These are the exceptions that trip up even confident learners. Once you've seen each one a few times, they stop being exceptions.

1. "I am" → "aren't I?"

Logically the tag for "I am" should be "am not I", but English speakers never contract am not that way. Instead, everyone uses the irregular form aren't I.

• I am right, aren't I?
• I'm late again, aren't I?
• I am invited too, aren't I?

2. Imperatives (commands and requests)

Sentences that give an order or make a request don't have a normal subject to flip, so they almost always take will you? A friendlier invitation uses won't you?, and a gentler request often uses could you? or can you?

• Close the window, will you?
• Pass me the salt, could you?
• Have some more cake, won't you?
• Don't be late, will you?

3. "Let's" → "shall we?"

Suggestions that start with Let's always take shall we?, no matter what the rest of the sentence looks like.

• Let's start the meeting, shall we?
• Let's not argue about this, shall we?
• Let's go for a walk, shall we?

4. "There is / There are"

Treat there as if it were the subject and keep it as there in the tag — don't switch it to it or they.

• There is a problem, isn't there?
• There aren't any tickets left, are there?
• There was a storm last night, wasn't there?

5. Indefinite pronouns → they / it

Words like everyone, someone, no one, everybody, somebody, nobody refer to people but are grammatically singular — yet the tag pronoun that follows them is almost always they. Words like everything, something, nothing take it.

• Everyone enjoyed the trip, didn't they?
• Somebody called earlier, didn't they?
• Nothing has changed, has it?
• Everything is ready, isn't it?

6. Hidden negatives (no "not" needed)

A statement can be grammatically negative in meaning without the word not anywhere in it. Words like never, hardly, rarely, seldom, barely, scarcely, few, little, no one, nobody, nothing make the whole statement negative, so the tag must still be positive.

• She never calls, does she?
• He hardly eats anything, does he?
• There is little time left, is there?
• No one knows the answer, do they?

7. "Used to" and "have to"

Used to behaves like a simple past verb, so it borrows did. Have to (meaning "must") behaves like an ordinary main verb, so it also borrows do / does / did rather than using have as the auxiliary.

• You used to live here, didn't you?
• She has to leave early, doesn't she?

Positive + Positive Tags (The One Real Exception)

Every rule above assumes the tag is used to check a fact or invite agreement. But native speakers do occasionally attach a positive tag to a positive statement — and when they do, it is never a real information question. It expresses surprise, sudden realization, interest, or sarcasm.

• "So you're getting married, are you?" — surprise / teasing interest, not a real question.
• "Oh, you think that's funny, do you?" — mild sarcasm or annoyance.
• "You've eaten my sandwich, have you?" — accusing tone, the speaker already knows the answer.

Because this pattern only exists to carry attitude, avoid it in neutral, polite conversation until your ear is trained enough to recognize the tone it needs — used flatly, it can sound rude.

How Tone Changes the Meaning

The exact same tag can be a genuine question or a simple request for agreement, depending only on whether your voice rises or falls at the end.

• Rising tone (↗) = a real question. The speaker is genuinely unsure and wants an answer. "You closed the shop, didn't you?" (rising — "I'm actually not sure, please tell me.")
• Falling tone (↘) = seeking agreement. The speaker already believes the statement is true and simply wants the listener to confirm it. "It's a beautiful day, isn't it?" (falling — "I already know it is; I just want you to agree.")

This is why question tags are so common in small talk: with a falling tone, they turn a plain statement into an easy, low-pressure way to start a conversation.

Subject → Tag Pronoun Reference

Whatever the subject of the statement is, the tag always uses a matching pronoun instead of repeating it.

Practice: Add the Correct Tag

Complete each sentence with the correct question tag:

1. "You haven't seen this movie, ______?" → have you
2. "Let's order some food, ______?" → shall we
3. "I'm invited to the party, ______?" → aren't I
4. "There isn't any milk left, ______?" → is there
5. "Nobody called while I was out, ______?" → did they
6. "Close the door, ______?" → will you
7. "She rarely complains, ______?" → does she
8. "They played well yesterday, ______?" → didn't they

Frequently Asked Questions

Summary

• Golden rule: positive statement → negative tag; negative statement → positive tag.

• "I am" → aren't I; "Let's" → shall we; commands → will you.
• Words like never, hardly, nobody, nothing already make a sentence negative — keep the tag positive.
• Positive + positive tags exist, but they show attitude (surprise/sarcasm), not a real question.
• Falling tone = agreement; rising tone = a genuine question.
