Adverbs

The normal way to form an adverb is to add -ly as in stupidly, publicly or humorously. However, there are exceptions:

If the word ends in -ll, add -y (e.g. fully).

For words of more than one syllable that end in -y, remove the -y and add -ily (e.g. happily).

Most single-syllable words ending in -y are regular, except for daily and gaily.
