This document discusses phrasal verbs in English. It begins by defining phrasal verbs as verb-particle combinations that form a new semantic unit. It then categorizes phrasal verbs as either transitive or intransitive, and further divides transitive phrasal verbs into separable and non-separable. Examples are provided for each category. The document also notes that some phrasal verbs can be both transitive and intransitive with different meanings. Phrasal verbs consisting of a verb and two particles are then introduced, followed by examples. The document concludes by discussing formality differences in phrasal verb usage and providing strategies for predicting phrasal verb meanings based on the particle.
