Different uses of auxiliary verbs

Syllabus topic 24: Different uses of auxiliary verbs

Different uses of auxiliary verbs. Auxiliaries form questions, negatives, emphasis and short responses.

How it works

Auxiliaries form questions, negatives, emphasis and short responses. Do can emphasise a simple-tense statement; so/neither use inversion for agreement. Repeat the appropriate first auxiliary rather than the entire verb phrase.

Examples in context

Notice how each form fits its sentence. Read the context before choosing a form.

  • I do understand your concern. (emphatic present)
  • She can swim, and so can I.
  • You haven't finished, have you?
  • He doesn't drive, but I do.
  • Was she working? Yes, she was.
