Adjectives that end in -ic, change the -ic to -al, and add -ly.

There are exceptions to the rule.

Adjectives that end in -e, just add -ly.
- rude - rudely
- live - lively
Adjectives that end in -le, drop the -e, and add -ly.
- accountable - accountability

Please note not all words that end in -ly, are not adverbs.
