An adverbial phrase is a group of words that functions as an adverb, modifying a verb, adjective, adverb, or even a whole clause. Adverbial phrases can be divided into two types: complement adverbs and modifier adverbs. Unlike adverbial clauses, adverbial phrases do not contain a subject and a verb. Adverbial phrases can be made up of two adverbs, and these are typically formed by adding a qualifier or intensifier before another adverb. Adverbial phrases serve a range of functions, including manner, place, time, and purpose. Examples of adverbial phrases include "in the morning" and "behind the shed".
