Adverbs

Most adverbs are formed from an adjective:
easy (-y) + ily      = easily              
complete + ly       = completely    
automatic + ally   = automatically        
horrible (-le) + ly  = horribly    
happy(-y) + ily     = happily          
nice + ly               = nicely            
romantic  + ally    = romantically          
simple   (-le) + ly  = simply


Some adverbs have the same form as an adjective:
close, daily, early, fast, hard, high, late, right
