A possessive noun is a type of noun that shows ownership or possession of something. It is a word that indicates that something belongs to someone or something else. Possessive nouns are typically formed by adding an apostrophe and the letter "s" to the end of a singular noun, or just an apostrophe to the end of a plural noun that already ends in "s".
Formation of Possessive Nouns

To form a possessive noun, you need to follow these rules: - For singular nouns, add an apostrophe and the letter “s” to the end of the word. For example, “cat” becomes “cat’s”. - For plural nouns that end in “s”, add only an apostrophe to the end of the word. For example, “cats” becomes “cats’”. - For plural nouns that do not end in “s”, add an apostrophe and the letter “s” to the end of the word. For example, “children” becomes “children’s”.
Examples of Possessive Nouns
Here are some examples of possessive nouns: - The cat’s toy is red. (Here, “cat’s” is a possessive noun showing that the toy belongs to the cat.) - The cats’ favorite food is tuna. (Here, “cats’” is a possessive noun showing that the food belongs to the cats.) - The children’s playground is closed. (Here, “children’s” is a possessive noun showing that the playground belongs to the children.)
| Type of Noun | Example | Possessive Form |
|---|---|---|
| Singular | cat | cat's |
| Plural (ends in "s") | cats | cats' |
| Plural (does not end in "s") | children | children's |

Common Mistakes with Possessive Nouns

One of the most common mistakes made with possessive nouns is the confusion between “its” and “it’s”. Its is the possessive form of “it”, showing that something belongs to it, whereas it’s is a contraction of “it is” or “it has”. For example: - The cat chases its tail. (Here, “its” shows that the tail belongs to the cat.) - It’s a beautiful day today. (Here, “it’s” is a contraction of “it is”.)
