Subject and Object Questions

OBJECT QUESTIONS

• These are the most common questions. Have a look at the structure:
  

Question Word + Auxiliary + Subject + Verb + Optional Object or Complement + ?
The Question Words are usually: what, where, when, who, why, which, how.

• Example: What did you see last Saturday evening on TV?

SUBJECT QUESTIONS

• These are not the most common but you can find them anywhere and at any time:

Question Word + Verb + Optional Object or Complement + ?
The Question Words can be WHO or WHAT, because they can be the subject of the question.
REMEMBER: Where, when, why (etc.) can't be the subject of any question.

• Example: "Who won the Eurovision Contest 2008?" "Russia". As you can see, the answer of the question is the IDENTITY of the QUESTION WORD "Who". That's why we call these questions SUBJECT QUESTIONS.
