I don't understand. A phrasal verb is a verb + preposition or adverb that has a meaning different from what the combination of the individual words mean. It is an idiom.
Student or Learner
My understanding of phrasal verbs are that they are intended to emphasize and intense the meaning or main verb? Can we omit the preposition and remain (more or less) same meaning?
