What type of noun names the person or thing that owns or has something?

A possessive noun is a noun that shows ownership, possession, origin or purpose for something in the sentence.

A possessive noun is formed by adding an apostrophe -s ('s) to the end of the Word, or just an apostrophe to plural nouns that already end with -s (s').

Examples:

Jim's bicycle (ownership, the bicycle belonging to Jim)

the children's smiles (possession, the smiles of the children)

Shakespeare's plays (origin, the plays by Shakespeare)

the ladies' room (purpose, the room designated for ladies)
