Adverbs

An adverb is a word which modifies a verb, an adjective or another adverb. Thus, in the example—"He writes well," the adverb shows the manner in which the writing is performed; in the examples—"He is remarkably diligent" and "He works very faithfully," the adverbs modify the adjective diligent and the other adverb faithfully by expressing the degree of diligence and faithfulness.

Adverbs are chiefly used to express in one word what would otherwise require two or more words; 'There' signifies in that place; 'usefully' signifies in a useful manner.

Adverbs, like adjectives, are sometimes varied in their terminations to express comparison and different degrees of quality. Some adverbs form the comparative and superlative by adding 'er' and 'est'; soon, sooner, soonest.
