caste

caste is feminine in French.

caste (hereditary class); class (social position)

Borrowed from Portuguese casta, if of Germanic origin, possibly from Gothic *𐌺𐌰𐍃𐍄𐍃 (*kasts), from Proto-Germanic *kastuz, from Proto-Indo-European *h₂ǵ-es- (“to throw”), similar to English cast. Or, alternatively from a derivative of Latin castus.
