Subject and Object Questions

Subject questions ask about who does an action.

Object questions ask about who receives an action.

In this lesson, you’ll learn about the difference between these questions, plus questions with prepositions and practise using them.

How to use subject and object questions?

Subject Questions

Used to ask about who/what does an action.
Structure – who/what + verb + object?
Do not use auxiliary verbs in subject questions (do/does/did).
Use the same word order as the positive statement. E.g. Who called you? Someone called you.

Object Questions

Used to ask about who/what receives an action. You already know who the subject is.
Structure – Who/What + auxiliary verb + subject + verb?
Use an auxiliary verb (do/does/did) in the question.
E.g. Who did you call? You called someone.
