In possessive nouns, possession is usually marked by what punctuation?

Possessive nouns indicate ownership or a relationship between nouns, and this relationship is typically marked by using an apostrophe. For singular nouns, the apostrophe is placed before the "s" (for example, "the dog's bone" indicates that the bone belongs to the dog). In the case of plural nouns that already end in "s," the apostrophe is placed after the "s" (for instance, "the dogs' park" indicates that the park belongs to multiple dogs).

Thus, understanding that the apostrophe is the correct punctuation for indicating possession helps clearly convey ownership in sentences. This is foundational in writing to avoid ambiguity and ensure clarity in communication regarding relationships between different entities.
