Rules for Adding Suffixes:
When do you change the letter y ?
When does the y stay the same?

The 'Change Y' rule, part 2:

A) If the suffix is ing or ish, do NOT change the y to i.

cry + ing = crying

copy + ing = copying

baby + ish = babyish

This is because English words do not have two i's together -
it wouldn't look right:

criing

copiing

babiish

crying

copying

babyish

B) If there is another vowel just before the y, do NOT change the y to i.

play + ed = played

donkey + s = donkeys

employ + employer

Again, it wouldn't look right to have so many vowels together:

plaied

donkeies

emploier

played

donkeys

employer

Now try these.
Sometimes you have to change the y to i but sometimes the y stays.

Add the suffix to the root word	Type the answer
monkey + s
enjoy + ing
worry + ed
joy + ous
glory + ous
dismay + ed
hurry + ed
moody + ness
jockey + s
berry + s
key + s
healthy + er
