Changing Rule for adding vowel suffixes

2. Vowel Y = long (e) & long (i) sounds
We have already learned the letter Y can be a consonant or a vowel.
We know vowel Y can make the long (e) sound, as in the words … carry and hurry
We know vowel Y can make the long (i) sound, as in the words….satisfy and multiply

3. Changing Rule
We know that a SUFFIX is a VOWEL SUFFIX if the FIRST letter of the suffix is a vowel.
-ing, -er, -ed
When you add a vowel suffix to a base word with vowel Y in the final position, you must change the Y to i before adding the suffix unless the suffix begins with the letter i.
Base Word: cry + ed = cried
cry + ing = crying
