Parts of Speech: Adverb

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 andadverbial clauses.

Demonstrative Adverb

Many languages have sets of demonstrative adverbs that are closely related to the demonstrative pronouns in a language. For example, corresponding to the demonstrative pronoun that are the adverbs such as then (= "at that time"), there (= "at that place"), thither (= "to that place"), thence (= "from that place"); equivalent adverbs corresponding to the demonstrative pronoun this are now, here, hither, hence. A similar relationship exists between the interrogative pronoun what and the interrogative adverbs when, where, whither, whence. See pro-form for a full table.

Conjunction

 A conjunction (abbreviated conj or cnj) is a part of speech that connects two words, sentences, phrases or clauses together. A discourse connective is a conjunction joining sentences.
