A possessive noun is a type of noun that indicates ownership or possession of an object, person, or concept.
It is formed by adding an apostrophe and the letter “s” (‘s) to the noun, or just an apostrophe (‘) after plural nouns ending in “s.”
For example, “John’s car” or “the students’ books.” Possessive nouns clarify who or what has ownership over something and help convey relationships and connections between individuals or entities and the objects they possess.
They are a fundamental part of grammar for indicating possession and ownership in written and spoken language.
