What does “do” mean?
To define the word, when you do something, this means you “perform, take part in, or achieve something: that was a really silly thing for me to do”.
When to use “do” or “does”?
Do is an irregular verb since its past tense conjugations do not end in the standard “-ed” that regular verbs take on. Additionally, do changes depending on whether the subject is in the first-person singular or third-person singular.
We use does for all third-person present singular subjects, such as the pronouns he, she, and it; e.g., She does the shopping on Wednesdays.
We use do, on the other hand, for all first-person singular subjects: I’m about to do the laundry.
| present | past | future | |
|---|---|---|---|
| simple | I do/does | I did | I will do |
| continuous | I am doing | I was doing | I will be doing |
| perfect | I have done | I had done | I will have done |
| perfect continuous | I have been doing | I had been doing | I will have been doing |
Verb tenses of ‘do’.
| base verb | past tense | past participle |

Did vs. does
Compare how the tenses of ‘do’ work in both sentences:
|
He does his schoolwork when he gets home from school. |
|
He did his homework when he got home from school. |
Did and does are simply two different tenses that we use to denote either the past or present time. The simple past tense of do is did for all subjects. The past participle form is done, also for all subjects.
Thus, the difference is did denotes the past, and do/does is in the present (in the first person/third-person singular).
Did vs. done
| Word Form | Examples |
|---|---|
| Other | He did a lot of homework today.
He had done a lot of homework before he went out with his friends. |
“He did a lot of homework today” is the simple past tense, and simply mentions an action that took place at a time before now.
The second sentence with ‘he had done’ includes the past participle ‘done’ + the auxiliary verb had, to form the past perfect tense. The past perfect, also called pluperfect, is a form of the past that depicts something that happened before something else which also occurred in the past.
‘Do’ as an auxiliary verb
To do is one of the three auxiliary verbs, along with to be and to have (not including modal auxiliaries). When ‘do’ is used in sentences with another verb, it’s probably taking on an auxiliary role:
|
We use do to make negatives (do + not), to make question forms, and to make the verb more emphatic. I didn’t see you at the concert the other night. Do they open at nine o’clock on weekdays? —Cambridge Dictionary. |
