A sentence expressed in a form which requires an answer. Two common types of questions exist: Yes-No questions and WH-questions.
- Are you coming with us?
- Who is she talking to?
Other types of questions also exist.
For example, the question Is it a bird or a plane? is a polar question.
The examples given above are all direct questions.
English also allows utterances which have the force of questions, even though they have the form of statements.
- You are coming with us? (uttered with rising intonation)
An expression like isn’t it? or don’t you? (consisting of auxiliary verb + pronoun subject) put on to the end of a sentence.
- It is a nice day, isn’t it?
- She doesn’t care, does she?
Question tags are used to check whether something is true, or to ask for agreement. We use a negative question tag after an affirmative sentence.
You are the new secretary, aren’t you?
We use a non-negative question tag after a negative sentence.
You aren’t the new secretary, are you?
