lol are you posting under several diff names for the same kinda homework?
yeah because there is a lot of questions but luckily i am almost done :)
Anon is right. You don't fool anyone by posting under different names.

What is the rule for adding a prefix for a word that ends in a consonant + y?

Look at multiply, tiny, family, rainy?

Check a dictionary (dictionary.com) for some suffixes for these words.
you take away the y and add an i and then add es and i am sorry :(
