Greek peprotai "it has been granted," Sanskrit purtam "reward," Hittite parshiya- "fraction, part").

It has replaced native deal (n.) in most senses. Theatrical sense (late 15c.) is from an actor's "share" in a performance (The Latin plural partis was used in the same sense). Meaning "the parting of the hair" is 1890, American English.
