The Rule:
* The "y" changes to "i" to maintain the soft sound of the "c" or "g" before the suffix.
Examples:
* happy + er = happier (The "y" changes to "i" because the "p" before it is a consonant.)
* try + ing = trying (The "y" changes to "i" because the "r" before it is a consonant.)
* cry + ed = cried (The "y" changes to "i" because the "r" before it is a consonant.)
Exceptions:
* If the suffix starts with "i," the "y" stays the same.
* baby + ish = babyish
* carry + ing = carrying
Key Points:
* The "y" only changes to "i" if it is preceded by a consonant.
* If the "y" is preceded by a vowel, it remains unchanged.
* Suffixes starting with "i" do not cause the "y" to change.
