A phrase that combines a verb with a preposition or adverb or both and that functions as a verb whose meaning is different from the combined meanings of the individual words.
Phrasal Verb:
take someone up
Meaning:
to discuss or deal with someone. (See also take something up.)
Example:
What are we going to do about Bill? Are we going to take Bill up today at the board meeting?
Phrasal verbs, also called two-word verbs, are idiomatic expressions wherein the second element of the verb (the adverb or particle) is not necessarily predictable.
