Questions with do, does and did 📕
Most English questions need a helping verb. If there is no other helping verb, we use do, does or did.
Form: (question word) + do / does / did + subject + base form
| Tense | Question |
| Present (I, you, we, they) | Do you like pizza? |
| Present (he, she, it) | Does she work here? |
| Past (all persons) | Did they call you? |
Where do you live?
What time does the shop open?
Why did you leave?
The main verb is in the base form
✗ Does she works here?
✓ Does she work here?
✗ Did you went home?
✓ Did you go home?
No do with be and modal verbs
With be, can, will, should and other helping verbs, just change the order:
Are you tired?
Can you help me?
Have you finished?
✗ Do you are tired?
Questions about the subject: no do
When the question word is the subject, we don't use do:
Who called you? (someone called you)
What happened?
✗ Who did call you?
