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.

An apostrophe followed by an “s” is used in English to create possessive nouns. For example, the noun dog becomes dog’s when you refer to something belonging to the dog, such as “the dog’s ball.” With plural nouns ending in “s,” you add the apostrophe after “s” and do not add an additional “s.”

An apostrophe (‘) is a punctuation mark that creates a contraction or shows ownership for a possessive noun. We use it after an S (s’) for plural nouns that show possession or singular nouns ending in S. You can also use it after the letter S as a possessive apostrophe for names or proper nouns ending in S.

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.

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.
