1. Definition
1.1. Adverb
1.1.1. An adverb is a word or an expression that modifies a verb, adjective, another adverb, determiner, clause, preposition, 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 is called the adverbial function, and may be performed by single words (adverbs) or by multi-word adverbial phrases and adverbial clauses.
