A possessive is a word or phrase that shows ownership or belonging. It's often indicated by an apostrophe, especially when referring to singular nouns or plural nouns that don't end in "s".
Here are some examples:
* The dog's bone (the bone belongs to the dog)
* My friend's car (the car belongs to my friend)
* The children's toys (the toys belong to the children)
