The document discusses phrasal verbs in English. It defines phrasal verbs as verbs that combine with particles like prepositions or adverbs to create an idiomatic meaning different than the individual words. Phrasal verbs can be separable or non-separable. Separable phrasal verbs allow separation of the verb and particle by an object, while non-separable phrasal verbs do not separate. Translating phrasal verbs to Indonesian can be difficult as their meanings are often non-literal combinations of the individual words.
