A phrasal verb is a verb combined with a preposition, adverb, or both to form a semantic unit. Phrasal verbs are common in English and often have meanings different from the individual words. There are two main types - particle verbs containing adverbs and prepositional verbs containing prepositions. The position of objects with phrasal verbs depends on whether it is a particle or prepositional verb and whether the object is a pronoun or noun phrase. Phrasal verbs are an important part of spoken English.
