If the word ends in -e, just add an -r:

large/larger

 

If the word is one-syllable, ends in a single consonant and has a single vowel before it, double the last consonant and add -er:
big/bigger

hot/hotter

thin/thinner

If the word ends in -y, remove it and add -ier:
angry/angrier

shiny/shinier

 

If the word ends in -e, add -r:
gentle/gentler

simple/simpler

 

If the word ends -ow; add -er:
