Phrasal verbs are combinations of a verb and one or more particles, usually prepositions or adverbs, that create a new meaning. For example, the verb take combined with the particle off forms the phrasal verb take off, which means to remove something or for an aircraft to leave the ground. These expressions are common in everyday English and can often be confusing for learners due to their idiomatic nature. Understanding phrasal verbs is essential for effective communication, as they are frequently used in both spoken and written language. They can vary in meaning depending on the context, such as give up meaning to stop trying or look after meaning to care for someone. Mastering phrasal verbs can enhance fluency and comprehension in English.
