Singular and Plural Nouns — Regular and Irregular

​Regular nouns become plural nouns by adding -s to the end of the word. If the singular noun already ends in s, ss, x, ch, or sh, write its plural form by adding –es to the end.

Always remember that in most cases, if a noun ends in a vowel followed by y, add -s to make them plural.

Irregular nouns are nouns that do not follow the simple rules of adding -s or -es. They usually change their spelling. If the singular noun ends in y, just change the y to i and add –es. If the noun ends with f, it usually forms its plural by changing f to v and adding -es.
