adverb

adverb (adverb): one of the lexical word classes. Adverbs are a very heterogeneous word class. Many are derived from adjectives, and are therefore largely descriptive or evaluative, and typically end in -ly (e.g. greatly, slowly). These can generally be compared for degree, using more/most. Others refer to such things as time, place and reason (e.g. now, yesterday, here, everywhere, therefore), while yet others may express connections between sentences (linking adverbs, e.g. however, so, nevertheless). Adverbs function as intensifiers in adjective phrases or adverb phrases, or as adverbials.
