Y to I Change – When the base ends in a consonant + y, change the y to i before adding -y.
happy → happier (comparative) but for the suffix itself: beauty → beautiful (different suffix).
For the -y suffix, this rule rarely applies because the base usually ends in a vowel or consonant not followed by y. -
Keeping the Final y – If the base already ends in y, simply add another -y, producing a double y.
