Adding endings to words that end in a double ‘l’

You need to drop the final l from words that end with a double l before adding endings that begin with a consonant (e.g. -ment, -ful, and -ly):

installinstalment
skillskilful
chillchilly

 

The ending -ness is an exception to this rule:

smallsmallness
illillness
