Explanation:
Phrasal verbs are verbs that consist of a verb and a particle and/or a preposition. Phrasal verbs are typical of spoken English or informal writing, e.g. letters to friends and articles in popular journalism. They cannot be understood based upon the meanings of the individual parts in isolation, thus, their meanings are unpredictable. The phrasal verb 'to go back' means 'to return'.
