The Greek "kharax" meant “pointed stake,” and its related verb meant “to cut, engrave, or sharpen.” A related noun was "kharaktÃer" (“engraved mark”), which slipped easily into English (via Latin and Old French) as "character." The “engraved mark” became a metaphor for that which marks one thing as different from another. Your character, then, is a “stamp” or “engraving” on your soul that sets you apart from others.
