The purpose of using an apostrophe in possessive nouns is to indicate ownership or possession. It is used to show that something belongs to or is associated with someone or something else. The apostrophe is placed before the "s" to indicate possession for singular nouns (e.g., the dog's bone) and after the "s" for plural nouns that already end in "s" (e.g., the dogs' leashes). It helps clarify the relationship between the noun and the object or person it possesses.
