In
grammar an
adverbial is a word (an
adverb) or a group of words (an
adverbial phrase or an
adverbial clause) that modifies or tells us something about the
sentence or the
verb. (The word
adverbial itself is also used as an adjective, meaning "having the same function as an adverb".) Look at the examples below:
- Danny speaks fluently. (telling more about the verb)
- Lorna ate breakfast yesterday morning. (telling when the verb's action occurred)
