Which part of speech never gets an apostrophe to indicate possession?

The part of speech that never gets an apostrophe to indicate possession is a pronoun.

Here's why:

* Pronouns are words that stand in for nouns (e.g., he, she, it, they, ours, yours).

* Apostrophes are used to show possession (ownership) of nouns.

Since pronouns already represent ownership (e.g., "his" book, "their" car), they don't need apostrophes.
