Question tags are short questions that are added to the statements or imperatives to turn into questions. The short questions such as ‘isn’t it, wasn’t it, didn’t you, aren’t I, do we, shall we, etc. are tag questions.
E.g. Ram’s engineer, isn’t he?
Shyam heard about his father’s death, didn’t he?
We use a negative tag for positive statement and a positive tag for negative statement.
Question tags are commonly used in English for two main functions:
The speaker expects the listener to know the answer and is asking a genuine question.
E.g. You met her yesterday, didn’t you?
The speaker may often know the answer.
E.g. His father was a doctor, wasn’t he?
Use the subject pronouns of the statements as the subjects of tags.
E.g. She works in a bank, doesn’t she?
If there are nouns, indefinite pronouns or two pronouns in the subject, replace them with single pronouns.
E.g. Bikram is a football player, isn’t he?
When we use a question tags with imperatives, we usually use ‘won’t’ for invitations and ‘can, can’t, will, would for orders. We generally use ‘will’ with negative imperatives.
Take a seat, won’t you? (polite)
Help me, can you? ( quite friendly)
Close the door, would you? (less friendly)
Do it now, will you? (less polite)
Don’t forget, will you?
Don’t sit here, will you?
Never do it again, will you?
