Wikipedia Meaning and Definition on 'Adverbs'
An adverb is a part of speech. It is any word that modifies any part of speech or other verbs other than a noun (modifiers of nouns are primarily adjectives and determiners). Adverbs can modify verbs, adjectives (including numbers), clauses, sentences and other adverbs.
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.
In English, adverbs of manner (answering the question how?) are often formed by adding -ly to adjectives. For example, great yields greatly, and beautiful yields beautifully. (Note that some words that end in -ly, such as friendly and lovely, are not adverbs, but adjectives, in which case the root word is usually a noun. There are also underived adjectives that end in -ly, such as holy and silly.)[See more about Adverbs at Dictionary 3.0 Encyclopedia]
