Here's how to identify possessive nouns:
* Apostrophe 's' : The most common way to form a possessive noun is by adding an apostrophe and the letter "s" ('s) to the noun.
* Example: *The dog's bone*, *The teacher's desk*
* Apostrophe only ' : If the noun is plural and already ends in "s," you only add an apostrophe.
* Example: *The students' books*, *The boys' toys*
* Compound nouns: For possessive compound nouns, add the 's to the last word of the compound.
* Example: *The mother-in-law's house*, *The editor-in-chief's office*
Examples of possessive nouns:
* John's car
* The cat's tail
* The children's toys
* My friend's birthday
* The company's policy
Possessive nouns are important because they help us understand who or what something belongs to.
