Why should we teach phrasal verbs?

English has a number of verbs used with particles. Examples are get up, take off, sit down, go out. These phrasal verbs are extremely common in everyday usage and are made with some of the most frequently used verbs and particles in English. The verbs include get, go, come, take, make, do, and the particles include words such as up, in, out, on, off, down. Here are some examples in sentences:

  • Are you going out tonight?
  • got up early this morning.
  • My flight takes off at 9am.
  • He put his coat on.

Phrasal verbs are closely related to prepositional verbs, which consist of a verb, a preposition and an object, for example, It depends on the weather; She looked at me. Sometimes, the two types are combined in phrasal-prepositional verbs, as in You have to face up to your responsibilities; I must get on with my essay.
