köken: From Low German slagge, slakke, from Middle Low German slagge, perhaps from slagen (“to strike”), from Old Saxon slegi, from Proto-West Germanic *slagi.
köken: From a local Vulgar Latin scauria, with the derivative scaureta already attested in Medieval Latin charters since the 9th century; perhaps from a substrate language, or from Latin scoria under the influence of a substrate.
Borrowed from Greek σκουρά (skourá), σκουριά (skouriá), from Ancient Greek σκωρία (skōría). See the doublets scoare (inherited from Latin) and scorie (borrowed from Latin and French).
