The pattern

The statement becomes a question by swapping the first two elements:

Nothing is inserted and nothing changes shape. This is the oldest question pattern in English, and be is one of the few verbs that still uses it.

Short answers cannot be contracted

Positive short answers always use the full form:

Yes, I am. — not Yes, I’m. Yes, she is. — not Yes, she’s.

Negative short answers do contract: No, she isn’t.

The question tag

The same verb comes back at the end of a statement to turn it into a check:

A positive sentence takes a negative tag and the other way round.

Telling the two patterns apart

Before asking a question, find the main verb:

If the verb is be, swap it. If it is anything else, bring in do or does.

Mistakes to avoid

Wrong: Do you ready? correct: Are you ready?

Ready is a description, so the verb is be, and be asks its own question.

Wrong: Is she is a doctor? correct: Is she a doctor?

The verb moved to the front. It cannot stay in its old place as well.

Wrong: Yes, I'm. correct: Yes, I am.

A short answer cannot end on a contraction. Use the full form.
