Hello Professor. When do we say ‘who met you?’ and ‘who did you meet?’? (Marine, France).
Hello Marine and thanks for that very common question we get from students and I’ll try my best to answer it. Take a look at the following sentence. What is the subject and object of the sentence?
- I met Javier
Remember, every sentence has a subject and verb and some verbs have objects. The subject of the sentence is ‘I ‘and the object is ‘Javier’. So if we want to know who ’met’ Javier (who did the action), we ask the question ‘Who met Javier?’ The wh-question word is followed by the verb and then the object. This is called a subject question. Clearly the answer is ‘I met Javier’.
However, if we want to know about the object ‘Javier’, we ask the question using the auxiliary verb ‘do’ in this case ‘did’ followed by the subject ‘you’ and the infinitive form of the verb ‘meet’ at the end. So what’s the question? Yes…, ‘Who did you meet?’
Look at the next example:
- She ate the apple
Here the subject question is ‘Who ate the apple?’ and the object question is ‘What did she eat?’ Obviously the object is a thing, so we use a different wh-question word, in this case ‘what’. We can use other wh-words such as which, where, when, how many and even why.
