Do - Does

What are do and does?

Do and does come from the verb To Do.

There are two ways to use the verb To Do: as a normal verb or as an auxiliary verb.

The difference between Do and Does

 We use do for
  •  I, you, we and they
So
  • I do exercise 
  • You do exercise
  • We do exercise
  • They do exercise
 We use Does for the third person singular
  • He/she/it
  • so that means also: my mother, Tom, the cat, his car, etc.
 So
  • He does exercise
  • She does homework
  • Tom does the dishes
  • My mother does the cleaning
  • His cousin does the gardening

 

In the case of My mother, be careful. The word my can be confusing, but my mother is still the third person singular and so you must put does.
