How do I use “do” and “does” in a question?


Do and does are the present tense forms of the auxiliary verb to do. When the subject of the sentence is he, she or it we use does. When the subject of the sentence is I, you, we or they we use do.

Below is the conjugation of the verb to do in the Present Tense.
I do
You do
He/she does
It does
We do
They do

The auxiliary verb can be used to form questions or negative sentences. To form a question the verb is usually placed before the subject. Here are some examples:

  • Do you speak English?
  • I don’t speak English.
  • Does he own a car?
  • He doesn’t own a car.
  • Does it snow in Ireland?
  • It doesn’t snow in Ireland.
  • Do we have a test today?
  • We don’t have a test today.

Remember we don’t use the verb to do in questions with the verb to be or modal verbs. For example:

  • May I go to the bathroom?
  • Are you going to the party?
  • Is he happy at school?
  • Should we help clean the house?
