When "y" changes to "ies" when we add "s" to a word!?

Hi every one;

When we add "s" to words like "study", the word changes to "studies". When we add "s" to destroy, it doesn't change and stays "destroys".
One said that if the letter before "y" was vowal it will not change, else it will changed to "ies". But in word "nationality", when we add "s" we wrote "nationalities". What's the reason? When we change "y" to "ies" and when not?

Thanks

For the third person singular form of lexical verbs and the plural form of nearly all nouns we add -s (or -es after words ending in –ss, -z, -sh, -ch –x and –o (but not –oo )). If the verb or noun ends in the letter -y following a consonant, we change the -y to i and add -es . destroy - destroys study -studies nation - nations nationality - nationalities.

Thanks you for your answer.
But my question is why "destroy" doesn't changed, and "nationality" changed?

o is a vowel and r is a consonant.

So is it depend on two letters before "y"? How they work? I mean if one was vowal and the othe was not, which one should be vowal and how they effect?

No. It depends on the letter immediately before -y:

destroy
nationality.

I think the normally perfect fivejedjon got a little mixed up this time. He meant the letter immediately before the "y"—the "o" in "destroy" and the "t" in nationality. His "r" in "destroy" and "r is a consonant" (concerning "nationality") were mistakes.

I don't think you are right there, ...

... and you are not really right there. I made a blunder. Thanks for pointing it out. My apologies for adding to your confusion, Bbk.
