Regular Plurals in English

Nouns in English have singular and plural forms. When you have only one of something, you use the singular form. When you have more than one, the noun must be in its plural form.

The general rule to create a regular plural is to add -s or -es to the end of the word. However, for some words, you must also change the spelling a little.

Let’s look at the regular plural of common words.
