Phrasal Verbs in English
In English, a phrasal verb is a phrase that indicates an action—such as turn down or ran into. The term applies to two or three distinct but related constructions: 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.
