Someone who has lived to be 100 years old, often marked by remarkable resilience.

means A person who has lived to be 100 years old or more.

from Built from Latin 'centenarius,' meaning 'relating to a hundred,' itself from 'centum' — the same root that gives us 'century' and 'percent.' The '-arian' suffix (as in 'vegetarian' or 'librarian') marks a person belonging to or defined by something, so a centenarian is, quite literally, 'a hundred person.' The word settled into English in the early 1800s as medicine and record-keeping finally let enough people live long enough to need the term.
