To show possession when the noun is plural and already ends in 's', you just add an apostrophe to the end of the word. You don't need to add an extra 's'. For example: The brothers' feet were muddy. The cats' fur is very fluffy.

Possessive apostrophes are apostrophes (’) used with the letter s at the end of a noun to show ownership over or a close connection with another noun. For example, if you were talking about the tail of your cat, you can add a possessive apostrophe and an s as punctuation to show which noun is the owner.

The only words that should ever show possession with an “apostrophe s” are nouns that show possession. Verbs, adjectives, adverbs, and other parts of speech should not be made possessive. That is, they should not have an apostrophe followed by an “s.” An apostrophe and an “s” should only be added to nouns to show appropriate possession.

One of the primary uses of the apostrophe is to indicate possession. When you want to show that something belongs to someone or something, you use an apostrophe. For example: John’s car The cat’s tail The children’s toys Note that the apostrophe is placed before the “s” when the noun is singular, and after the “s” when the noun is plural.

Apostrophes are used in possessive nouns to indicate that something belongs to something or someone else. To indicate possession with a singular noun, add an apostrophe “s” ’s at the end of the word. This also applies to names and other proper nouns.
