An adverbial phrase is a group of words that functions as an adverb in a sentence, providing additional information about the verb, adjective, or adverb.
It typically answers questions like how, when, where, why, or to what extent.
Examples include: “in the morning” (when), “with great enthusiasm” (how), and “at the park” (where).
Adverbial phrases enhance the details of an action or modify other parts of a sentence, contributing to a more precise and nuanced expression of the intended meaning.
