An adverb is a word that modifies a verb, adjective, another adverb, determiner, noun phrase, clause, or sentence. Adverbs typically express manner, place, time, frequency, degree, level of certainty, etc., answering questions such as how?, in what way?, when?, where?, and to what extent?. This function is called the adverbial function, and may be realised by single words (adverbs) or by multi-word expressions (adverbial phrases and adverbial clauses).
Adverbs are traditionally regarded as one of the parts of speech. However, modern linguists note that it has come to be used as a kind of "catch-all" category, used to classify words with various different types of syntactic behavior, not necessarily having much in common except that they do not fit into any of the other available categories (noun, adjective, preposition, etc.)
The English word adverb derives (through French) from Latin adverbium, from ad- ("to"), verbum ("word", "verb"), and the nominal suffix -ium. The term implies that the principal function of adverbs is to act as modifiers of verbs or verb phrases. An adverb used in this way may provide information about the manner, place, time, frequency, certainty, or other circumstances of the activity denoted by the verb or verb phrase. Some examples:
Adverbs is a 2006 novel by Daniel Handler. It is formatted as a collection of seventeen interconnected narratives from the points of view of different people in various sorts of love. Each of the titles is an adverb suggesting what sort of love the people are dealing with. Some people are "wrongly" in love, others are "briefly" in love, and so on. The book focuses on the ways that people fall in love, instead of focusing on whom they are in love with.
Adverbs is billed as a novel, but is commonly described by critics and journalists as a collection of short stories. Certainly it breaks some of the traditional conventions of the novel genre. The narrative is driven by half-truths and intentionally misleading statements. The point of view shifts from story to story, characters reappear in unlikely settings, multiple characters have the same name, and Handler himself frequently makes an appearance, not in the role of the narrator, but apparently as the author himself.
