DO-variants

‘Do’ has five grammatical variants which are:

            Do

            Does

            Did

            Doing

            Done

Consider the tense table blow

Present(plural)	present(singular)	continuous	past	perfect
Do	does	doing	did	done

Let’s use the above in five different sentences.

I)                    They do fight always

II)                  She does walk majestically

III)                They are doing it right now

IV)               We did eat rice yesterday

V)                 We have done it

Note:

Among the Do-variants, ‘doing’ and ‘done’ are anomalous because they act as the main verbs. Likewise, the rest of Do-variants are capable of acting as the main verbs. For example:

I)                    He does his assignment so quickly

II)                  We did the work ourselves

III)                I can do it well
