Adverb

1. An Adverb qualifies any part of speech except a noun or pronoun, but it usually qualifies a verb, and adjective, or another adverb.

Examples : -- 

( a ) He runs fast 

( b ) He runs very fast 

( c ) He is quite happy. 

  

In ( a ) the adverb " fast " qualifies the verb " run " ;  

in ( b ) the adverb " very " qualifies the adverb " fast " ; and  

in ( c ) the adverb " quite " qualifies the adjective " happy ".
