köken: Either borrowed from Latin scoria, from Ancient Greek σκωρία (skōría), or possibly a popular continuation of a Vulgar Latin scauria, an Iberian variant of this word.
köken: From Neapolitan and Sicilian lava (“lava; downpour overflowing the streets”), likely from Latin lābēs (“a fall; a collapse; subsidence”), from lābī (“to fall; to slip”); compare lābīna (“landslide”).
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.
