An Adverb is a word which modifies or adds to the meaning of a verb, an adjective, or another adverb.
Adverbs may be divided, according to their use, into the following classes:-
TIME – before, now, since, then, already, soon, seldom
Example:- We have met before
PLACE – here, there, everywhere, nowhere.
Example:- They came here yesterday.
MANNER – badly, easily, slowly, well.
Example:- The tall boy won easily.
DEGREE – almost, much, only, quite, very, rather
Example:- The old lady walked very slowly.
NUMBER – once, twice.
Example:- They ran twice round the playground.
QUESTIONING – where, when, how.
Example:- When did you see him?
AFFIRMATION and NEGATION – yes, certainly, no, not
Example:- She can certainly swim.
I have not read the book
(Many adverbs are often used as connecting words and therefore become conjunctions.)
NOTE – The majority of Adverbs are formed from corresponding Adjectives by adding –ly, e.g. quickly, bravely, seriously, happily, clearly, slowly, quietly, angrily, fatally, suitably.
