If the word ends in "y" preceded by a consonant, change the "y" to "i" before adding any suffix except "ing" and "es".
Examples:
* happy + -ness = happiness (The "y" changes to "i" before adding "-ness")
* cry + -ed = cried (The "y" changes to "i" before adding "-ed")
* try + -ing = trying (The "y" remains the same when adding "-ing")
* fly + -es = flies (The "y" remains the same when adding "-es")
Exceptions:
* Some words retain the "y" before adding suffixes like "-ing" and "-es" if the word is a proper noun or if the "y" is preceded by a vowel.
* baby + -ing = babying
* monkey + -es = monkeys
* boy + -s = boys
Important Note: This rule only applies to words ending in "y" preceded by a consonant. If the "y" is preceded by a vowel, the "y" remains the same when adding suffixes.
