Forming adverbs

Many adverbs are formed from adjectives and end in -ly. Here are some tips to help you form adverbs and spell them correctly: 

•  The basic rule is that -ly is added to the end of the adjective:

adjective	adverb
quick	quickly
sudden	suddenly
straightforward	straightforwardly

•     If the adjective has two syllables and ends in -y, then you should change the -y to an i and then add -ly:

adjective	adverb
happy	happily
hungry	hungrily
lazy	lazily

•    If the adjective ends with a consonant followed by -le, replace the final -e with -y on its own:

adjective	adverb
terrible	terribly
comfortable	comfortably
incredible	incredibly
