Yes-No Questions English (Grammar)

This is the (Grammar) version of Yes-No questions. Are you looking for the Yes-No Questions Present Tense Simple version? Or maybe the Yes-No Questions Past Tense Simple version?

Technically, there are three types of Yes-No questions in English:

  1. Inverted questions (ex. Are you happy?)
  2. Inverted alternative questions (ex. Are you happy or sad?)
  3. Tag questions (ex. You’re happy, aren’t you?)

1. Inverted Questions

To make an inverted question the verb must be either a modal (can, could, may, might, must, ought, shall, should, will, would) or a helping verb (do, be, have, use). Simply switch (invert) the subject and the verb of the matching sentence.


Sentence: He can swim really well. (*can = modal can)
Question: Can he swim really well?

Sentence: He is a teacher. (*is = helping verb be)
Question: Is he a teacher?

Sentence: He doesn’t like drinking beer. (*doesn’t = helping verb do)
Question: Doesn’t he like drinking beer?

2. Inverted Alternative Questions

Inverted alternative questions are just like inverted questions except they include an alternative (another option). The answer may require more than a simple yes or no as an answer.

  • No, he doesn’t drink either.
  • Yes, he likes drinking beer, but usually he drinks wine.

3. Tag Questions

Tag questions are short questions added at the end of a sentence. Tag questions are often used to verify that something is true. Tag questions usually consist of a modal or helping verb and a subject pronoun (repeating the subject of the sentence).

*Tricky part: If the main verb is be, then we also use the correct form of be in the tag question.


  • This Saturday the team will play baseball, won’t they? (*will = modal, so use won’t.)
  • You‘re not leaving now, are you? (*be = helping verb for the main verb leave, so use are.)
  • That‘s coffee, isn’t it? (*be = main verb, so use isn’t.)

If there is no modal or helping verb in the sentence (only a main verb), then the tag question will use the correct form of the helping verb do.

  • He walks to work, doesn’t he? (*main verb = walks, so tag question uses does.)
  • The children opened all of their presents, didn’t they? (*opened = past tense, so the tag question uses did.)
  • You and I didn’t go to the same high school, did we?
