Adverbs of manner are the largest group of adverbs. Some of them can be used as either adjectives or adverbs. Although the list of adverbs of place is somewhat extensive, it is essential that you know some:
1. When the adjective ends in -le preceded by a consonant, the final –e is usually changed to -y. For example:

agile – agilely / sole – solely
3. When the adjective ends in –ll, only –y is added.For example:
dull – dully / full – fully
4. When the adjective ends in –ue, we omit the final –e and add –ly.For example:
due – duly / true – truly
5. When the adjective ends in -y preceded by a consonant, the -y is usually changed to –i before –ly.For example:
happy – happily / easy – easily
6. When the adjective ends in -y preceded by a vowel, we simply add –ly to the adjective.For example:
coy – coyly / grey – greyly
