Typological Characteristics of the Adverb in English and Ukrainian

An adverb is a word that changes or qualifies the meaning of a verb, adjective, other adverb, clause, sentence or any other word or phrase, except that it does not include the adjectives and determiners that directly modify nouns. Adverbs are traditionally regarded as one of the parts of speech, although the wide variety of the functions performed by words classed as adverbs means that it is hard to treat them as a single uniform category.
Adverbs typically answer questions such as how?, in what way?, when?, where?, and to what extent?. This function is called the adverbial function, and is realized not just by single words (i.e., adverbs) but by adverbial phrases and adverbial clauses.
