Damned if I know, but feel free to go through whatever De Re Militari has on the topic; some articles include discussion on old Byzantine words on various things, but dunno if this is among them. One article fairly directly relating to the subject I found is this; be warned, its editing and format is absolutely horrible and you're better off saving the thing and reading it in Word or something similar that helpfully arranges the lines in a semi-ergonomic fashion.
