Adverbial phrase
From Wikipedia, the free encyclopedia
An adverbial or adverbial phrase is a linguistic term for a single adverb or a group of more than one word operating adverbially, when viewed in terms of their syntactic function.
Compare the following sentences:
- I'll go to bed soon.
- I'll go to bed in an hour.
- I'll go to bed when I've finished my book.
In the first, soon is an adverb (as distinct from a noun or verb), and it is an adverbial (as distinct from a subject or object). Clearly, in the second sentence, in an hour has the same syntactic function, but does not contain an adverb; so a preposition, an article and a noun can function together as an adverbial. This is an adverbial phrase. In the third sentence, we see a whole clause functioning as an adverbial. It could also be called an adverbial phrase, but is more likely to be described as an adverbial clause.
Adverbial phrases sometimes consist of a pair of adverbs. Extra adverbs are called intensifiers:
- oddly enough
- very nicely
An adverbial phrase can modify a verb phrase, an adjectival phrase or an entire clause.
