    We use subject questions when we are asking about who, what, etc., did the action. We do not use an auxiliary verb after the question word if the question word (who, what, etc.) is the subject of the sentence.

    • Who did win the match? blank
    • Who won the match? blank
    • What did happen last night? blank
    • What happened last night? blank
    • How many people did go to the party? blank
    • How many people went to the party? blank

    When we are asking about the object (after the verb), we use the normal order of the English question: auxiliary verb + subject. These types of questions are called object questions.

    Object question vs subject question

    Jack called Teresa. (Teresa = object) Jack called Teresa. (Jack = subject)
    Who did Jack call? (Who = object) Who called Teresa? (Who = subject)

    Questions with preposition

    In informal or spoken English, when a question word needs a preposition, the preposition goes at the end of the question (after the verb or after verb + object if there is an object). We don’t use the preposition at the beginning.

    • I played tennis with John.  Who did you play tennis with
    • I work for a multinational company   What company do you work for?
    • We usually talk about sports. What do you usually talk about
