If a noun ends in a sound that sounds like a hiss or a buzz, we add -es to make a new syllable so the plural is easier to say. For example, 'foxs' is hard to say, but 'foxes' is easy. The Y to -IES Rule If a noun ends in a consonant + y, change the y to i and add -es. Look at the letter right before the final 'y'. If it's a consonant (like b, d, r, t), use this rule.
