The invariable Word class that acts as the core of the adverbial phrase or as background of the verb complement is known as an adverb. These words modify adjectives, verbs, or other adverbs.
There are different types of adverbs that add circumstantial information to a word or a complete sentence. 'Now', 'far', 'tomorrow', 'difficult' and 'quickly' are adverbs of different class.
