Adverbials:
Adverbials modify or tell us something about the sentence or the verb. It may be a single adverb, a phrase, or a prepositional phrase, or clause element.
When an adverbial modifies a verb, it changes the meaning of that verb.
For example:
- The students looked at me.
- The students looked at me fearfully (The verb looked suddenly has a very different meaning).
When an adverbial modifies a sentence, the meaning of the sentence changes.
For example:
- I attained all my goals.
- Surprisingly, I attained all my goals.
Word groups that are also considered to be adverbials can also modify verbs: a prepositional phrase, a noun phrase, a finite clause or a non-finite clause.
Multi-word adverbials are sometimes called adverbial phrases.
For example:
- I drove as quickly as I could, but I missed the flight.
- If a whole clause acts as an adverbial, it's called an adverbial clause.
For example:
- I'll go to bed when the show ends.
