פַּרְהַנְגַּרְיָא f. (parangaria, v. אַנְגַּרְיָא) a public service over and above that which one is bound to render, extra service (which is paid for). Gitt. 44ᵃ המוכר עבדו לפרהנג גוי וכ׳ Ar. (ed. נכרי, read: לפרהנגריא) if a man sells (rents out) his slave for extra service, he becomes a freedman (after he is dismissed from the service). Ib. בפ׳ שאינה חוזרת it means the service in an expedition that does not come back to the same place (so that the owner lets the slave go out of his control).
