This document discusses phrasal verbs in English. It explains that phrasal verbs are idiomatic expressions formed by combining verbs with prepositions or adverbs. This can result in new meanings that are different from the individual verb definitions. Phrasal verbs are widely used in both written and spoken English. Examples are provided to illustrate different types of phrasal verbs, including verb + preposition + object, adverbial particle + verb + object, and verb + adverbial particle + preposition + object. The document also discusses prepositional verbs, which contain a preposition that is always followed by a nominal object.
