The conjugation of the verb To Do
The verb To DO (pronunciation: tʊ dʊ) can be used as both a main verb
and an auxiliary verb, sometimes together in the same sentence.
For example: How do you do Mr. Smith?
As a main verb, it means:
- To perform an action – for example: Have you done your homework?
- To take part in an activity – for example: I do yoga on Monday evenings.
- To perform a song, dance or play – for example: I’d like to do one of my own songs next.
