Skrupskas

Cf. Skrupskys (see), Latv. Skrupskis ¹. The origin is unclear. Perhaps it is glorified (suffix -sk-) some Lithuanian surn., connected with lit. scrūpis „rupūžė, krupis“, scrūpis „skriausti, kamuoti“ (LKŽ XII 1101) or similar. Cf. still bend Skrupisz, Scrupis (SSNO V 100), Russian. Cкpупская (fem.) (CAМC IV 153).
