If an adjective has one syllable, you make the comparative form by adding "er" to the end:
brown -> browner
green -> greener
red -> redder (double 'd')
cold -> colder
hot -> hotter (double 't')
If an adjective has 2 syllables and it ends in 'y', you change 'y' to 'ier':
sunny -> sunnier
funny -> funnier
cloudy -> cloudier
windy -> windier
if an adjective has 2 or more syllables, you put 'more' at the beginning:
purple -> more purple
wonderful -> more wonderful
interesting -> more interesting
