we

--feedback--

This word is the subject of the tag question, matching the subject of the main sentence.

--explanation--

Tag questions are short questions added to the end of a sentence. They are used to confirm information or ask for agreement. A tag question includes a helping verb and a pronoun that matches the subject of the main sentence. The verb in the tag question must match the verb tense of the main sentence.

Haven't and hasn't are negative contractions of have and has, used in tag questions to confirm or check information.

Use haven't when the subject is plural (like we or they) or when the subject is I. Use hasn't when the subject is singular (like he, she, or it). For example:

• We've been working hard, haven't we? - The main sentence uses we've (we have), so the tag question uses haven't we? to confirm the statement.

• She's finished her report, hasn't she? - The main sentence uses she's (she has), so the tag question uses hasn't she? to confirm the statement.
