This document provides rules for forming plural nouns in English. It explains that most nouns form the plural by adding -s, but there are exceptions for nouns ending in certain letters like x, z, ch, sh which add -es. It also discusses changing the ending y to i and adding -es for some nouns and just adding -s for nouns ending in a vowel + y. Some nouns like fish or sheep remain the same in both singular and plural.
