Short questions tagged at the end of statements are called
question tags.
Look at the examples below:
a. You’re good at French, aren’t you?
b. Bindu wasn’t feeling well, was she?
→In the first sentence, the short question, aren’t you? is used to
check whether the statement ‘you’re good at French’ is true or
not.
In this sentence, the statement is affirmative and the question
tag is negative.
→In the second sentence, the short question, was she?, is used
to seek the listener’s agreement.
In this sentence, the statement is negative and the question tag is
affirmative.
