The Y Rule - School Specialty

The Y rule: When a root ends in y, change the y to i when adding a suffix (easy + est = easiest; happy + ness = happiness). Exceptions: Keep the y if a vowel comes before it (play + er = player; joy + ful = joyful). Keep the y if adding the suffix -ing(cry + ing = crying; study + ing = studying). Add suffixes or plural endings to the roots.
