Phrasal verb

In English, a phrasal verb is a phrase such as turn down or ran into which combines two or three words from different grammatical categories: a verb and a particle and/or a preposition together form a single semantic unit. This semantic unit cannot be understood based upon the meanings of the individual parts, but must be taken as a whole. In other words, the meaning is non-compositional and thus unpredictable. Phrasal verbs that include a preposition are known as prepositional verbs and phrasal verbs that include a particle are also known as particle verbs. Additional alternative terms for phrasal verb are compound verb, verb-adverb combination, verb-particle construction, two-part word/verb or three-part word/verb (depending on the number of particles) and multi-word verb.

There are at least three main types of phrasal verb constructions depending on whether the verb combines with a preposition, a particle, or both. The phrasal verb constructions in the following examples are in bold. The aspect of these types of verbs that unifies them under the single banner phrasal verb is the fact that their meaning cannot be understood based upon the meaning of their parts taken in isolation: the meaning of pick up is distinct from pick; the meaning of hang out is not obviously related to hang. When a particle verb is transitive, it can look just like a prepositional verb. This similarity is source of confusion, since it obscures the difference between prepositional and particle verbs. A simple diagnostic distinguishes between the two, however. When the object of a particle verb is a definite pronoun, it can and usually does precede the particle. In contrast, the object of a preposition can never precede the preposition.
