Phrasal verbs are one of the most difficult aspects of the English language, yet they are very important for learners because they are prevalent in spoken and informal written communication. Learning phrasal verbs can be tricky because in many cases the meaning of phrasal verbs cannot be deduced from its elements. For example, it might be a little difficult for a learner to decipher that to ‘give up’ something means ‘abandoning’ something, as he just knows that to ‘give over’ something means to ‘handover’ something to someone.
A phrasal verb is a combination of a verb and a preposition, a verb and an adverb, or a verb with both an adverb and a preposition. It has a meaning which is different from that of the original verb. Phrasal verbs are used mainly in spoken English and informal texts. They are generally not used in academically oriented work.
