VERB TO DO: Spelling, uses and meanings.

THE VERB TO DO.


As you may probably know, the verb TO DO might be used either as a main verb or as an auxiliary one to form other verbal tenses (past) and also: questions, negative sentences and short answers. We will see all this in detail later on.  First of all, let's see how the verb is written according to the  personal pronoun it follows:

In the positive :

In the negative and the interrogative forms, this verb is used as an auxiliary one to help other verbs to form negative and interrogative sentences.
