What does centenarian mean?

A centenarian is someone who is 100 years old or older.

Centenarian can also be used as an adjective to describe someone who’s 100 or older, as in The ceremony honored centenarian veterans, or things related to such a person, as in I have entered my centenarian years. 

It’s one of several similar terms used to refer to a person of a certain age, including quadragenarian (40s), quinquagenarian (50s), sexagenarian (60s), septuagenarian (70s), octogenarian (80s), and nonagenarian (90s).

Someone who is 110 years or older can be called a supercentenarian. Actually, if you’re 110 or older, you can be called whatever you want.

Example: I can’t believe I’m going to be a centenarian—tomorrow I turn 100!

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.
