How to form Subject or Object questions
See VIDEO for an explanation: Object questions or Subject questions? – video lesson
In Subject questions it is not possible to use an auxiliary to form the question.
We ask: Who made this cake? and not
Who did make this cake?
We cannot use an auxiliary verb (do, does, did) to ask a subject question because the standard question form with an auxiliary requires
- Auxilary verb + subject + principle verb
- Where do you go on Saturdays?
- Who did they give the prize to last week? (object question)
If we do not know the subject we cannot use this system.
Object or Subject questions?

did you sell
