Where does centenarian come from?

Centenarian comes from the Latin word centenāri(us), from centēn(ī), meaning “a hundred each,” from cent(um), “one hundred.” The suffix -an is used to indicate a person (as seen in common words like pedestrian and historian).

Living to be 100 is becoming more common, but it’s still somewhat rare. The word centenarian is often used in celebration of the achievement, or as a fancy or fun way of referring to someone of that age. As much fun as it is to say, it’s perhaps more often used in writing. It’s also used in the context of highlighting a person who’s doing something that may be surprising for their age, as in These centenarians who still exercise every day never cease to impress me.
