Rule #1
The plural of nouns is usually formed by adding - s to a singular noun.

cat-cats
fork-forks
flower-flowers
pen-pens

Rule #2
Nouns ending in s, z, x, sh, and ch form the plural by adding - es.

moss-mosses
buzz-buzzes
box-boxes
dish-dishes

If you add - s to such nouns as fox, bush, and bench, you will find that you cannot pronounce them without making an additional syllable. This is why such nouns form the plural by adding - es.
