When do we use the auxiliary verbs “Have” and “Do”?

H. Adjei. English/French teacher at AIT Language School

Los verbos auxiliaries, que en inglés se conocen como auxiliary verbs, se utilizan en combinación con verbos principales de la oración para formar oraciones negativas e interrogativas, para formar tiempos compuestos o continuos y, también para formar la voz pasiva.

Aunque como auxiliares no tienen significado propio, pueden funcionar como verbos principales si van solos.

Estos verbos auxiliares son be, do, have y will.

Hoy hablaremos sobre cuándo y cómo usar have y do.

Verb “have”

The verb “have” means “tener” but as an auxiliary verb it has no meaning.

We use the auxiliary verb “have” in perfect tenses. For example:

  • I have eaten a sandwich.
  • We have done a lot so far.
  • I have been following you for a mile.
  • She had been queen of the town.

Verb “do”

The verb “do” means “hacer”, but as an auxiliary verb it means nothing.

We use “do” in present simple and past simple. For example:

  • Do you live in Barcelona?
  • Did Jenny and Kim work together?
  • My parents don’t speak Japanese well.

Remember that “do and don’t” becomes “does” and “doesn’t” for the third persons (she, he, it).

  • Does she live in Barcelona?
  • Does your dog like bones?
  • My uncle doesn’t drive so, he takes the bus to work every day.
