Here are some ways nouns become plural:
* Adding -s: This is the most common way to make a noun plural, e.g., cat - cats, book - books, tree - trees.
* Adding -es: This is used when the noun ends in -s, -x, -ch, -sh, or -z, e.g., bus - buses, box - boxes, church - churches, dish - dishes, buzz - buzzes.
* Changing the ending: Some nouns have irregular plural forms, e.g., child - children, foot - feet, man - men, tooth - teeth, mouse - mice.
* Staying the same: Some nouns have the same form for both singular and plural, e.g., sheep, deer, fish.
Examples:
* Singular: One cat, one book, one tree
* Plural: Two cats, several books, many trees
Knowing how to form plurals is essential for correct grammar and communication.
