This morpho-lexical type designates ZIGER in Francoprovençal and Occitan. The type can be traced back to *sēracea, the fem. form of the adjective derivation of lat. sĕrum 'whey' (cf. Georges under serum). There also is a masculine variant (frp. seraz) documented in the FEW under *sēraceum which migrated into Standard French in the form of sérac (with a purely graphic final sound -c). A derivative of this was, in turn, borrowed into gsw. (Alemannic) (cf. Idiotikon under Rescherack ‘gesalzener Ziger’).
