# centagenarian

> English word · Noun

## Definitions
1. A centenarian.

## Etymology
Incorrectly formed by analogy with words like octogenarian (from octōgintā (“eighty”)) and nonagenarian (from nōnāgintā (“ninety”)). However there is no "centaginta"; the correct Latin is centum (“one hundred”)).
