The Spelling Rules for Adding Suffixes:

When do you change the letter y ?
When does the y stay the same ?

Teaching point - learning to spell

If you are adding the suffixes -ing or -ish to a word ending in y, you do not need to change the y to i. This is so there isn’t double i in the word.

For example:

If the suffix is ing or ish do not change the y to i – otherwise you end up with words with double i in them!

If there is another vowel just before the y, you also do not need to change the y to i. This is so there aren’t too many vowels clumped together in the word.

For example:

plaied
donkeies
emploier
played
donkeys
employer
