asco

There are at least two hypotheses:

• Inherited from a deverbal formation derived from Vulgar Latin *ōsicāre, from Latin ōdī (“to hate”). Compare Spanish usgo (“disgust”).
• Inherited from Latin eschăra (“scab, scar”), from Ancient Greek ἐσχάρα (eskhára, “hearth, brazier, scab”), cognate to English eschar, scurf, scar.

asco m (plural ascos)

1. nausea (strong dislike or disgust)

   Synonyms: desgosto, repulsão

• IPA^(key): /ˈasko/ [ˈas.ko]
• Rhymes: -asko
• Syllabification: as‧co

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”). 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.
