noun, masculine/ˈasko/plural: ascos
disgust; nausea; disgusting person
“¡Qué asco!” — Gross!
Per Roberts, probably inherited from Old Spanish usgo (“disgust”), back-formed from *osgar (“to loathe”), from Vulgar Latin *ōsicō, from Latin ōsus, perfect passive participle of ōdī (“to hate”), with influence from asqueroso. An alternative hypothesis derives this word from Latin eschăra (“scab, scar”), from Ancient Greek ἐσχάρα (eskhára, “hearth, brazier, scab”), cognate to English eschar, scurf, scar.
