An adverb is a word used to modify or describe an adjective, a verb, or another adverb. Adverb express particularly matters of time, manner of acting or doing, place and the like.
Rules of using Adverb:
Rule 1. The adverbs, sometimes, seldom, often, always, never, ever, frequently, rarely are placed before verbs they qualify. But these adverbs are placed after ‘to be'.
Rule 2.The adverbs, only, merely, chiefly, solely and some others are placed immediately before the word they qualify.
Rule 3.Too and Enough.
(a)‘Too' means more than ‘enough'. It should not be used in place of ‘very' or ‘much'.
(b)When ‘too' is followed by an infinitive, it implies a negative suggestion.
(c)Enough means according to the proper limit. Ad an adverb it is always placed immediately after the adjective it qualifies.
(d)‘Too' means “more than enough" while ‘enough' means that proper limit has been reached. ‘Enough' is placed immediately after the adjective it modifies, but too is placed before the adjective it modifies.
Rule 4. ‘Seldom or ever' is not a correct expression. The correct expressions are ‘seldom or never' and ‘seldom if never'.
Rule 5. Much, Very, Quite.
(a)‘Very' is used with Present Participles, with the Positive degree of non-verbal adjectives and with Past Participles established as independent adjectives.
(b)Much is used with Past Participles and Comparative and Superlative degrees.
(c) ‘Very' means ‘in great degree'. ‘Quite' means ‘completely' or ‘wholly'.
Rule 6. ‘Only' can be used as an adverb and also as an adjective. There should be no confusion in its use.
Rule 7. We should never use an adjective in place of an adverb or vice-versa.
