Question word order
Inversion in questions, and where the Wh-word sits.
Wh-word + Aux/Modal + S + V (+ O)
In yes/no questions, the auxiliary or modal moves before the subject: Aux/Modal + S + V. In wh-questions, the question word comes before that construction.
Examples
- Do you have the updated rate sheet?
- Have you seen the signed BOL?
- Can she confirm the pickup window?
You have seen it?
Have you seen it?
In a question the auxiliary have moves to first position: Have you seen.
Common mistakes
- A question without inversion, relying on intonation in writing: You have seen it? → Have you seen it?
- Adding do where a modal already carries the question: Do you can drive? → Can you drive?
