What do you call the punctuation used to clarify possession in writing?

The punctuation used to clarify possession in writing is called an apostrophe. Apostrophes indicate ownership by attaching to a noun. For example, in the phrase "the dog's leash," the apostrophe followed by the letter "s" shows that the leash belongs to the dog. This use of apostrophes helps readers understand the relationship between nouns and clarify who or what possesses something, which is essential for clear communication in writing. Other punctuation marks such as quotation marks, commas, and semicolons serve different purposes, like indicating dialogue, separating items in a list, or linking independent clauses, but they do not indicate possession.
