# Plethon

> English word · Proper noun · IPA /ˈpliːθɒn/

## Definitions
1. Georgios Gemistos Plethon (c. 1355–1453), a Byzantine Greek philosopher.

## Etymology
Borrowed from Byzantine Greek Πλήθων (Plḗthōn), adopted by Plethon as a nickname or cognomen from Attic Greek πλῆθος (plêthos, “multitude, great number”) as a classicizing substitute for his surname Γεμιστός (Gemistós), from γεμιστός (gemistós, “filled, stuffed”). The particular form may have been chosen to mirror Πλάτων (Plátōn, “Plato”).
