asco

From Proto-West Germanic *askijō.

asco m

1. grayling

• Middle High German: asche, esche
  • German: Äsche f
• → Italian: lasca f

• “Äsche” in Duden online
• Friedrich Kluge (1883), “Asche”, in John Francis Davis, transl., Etymological Dictionary of the German Language, published 1891

• Rhymes: (Brazil) -asku, (Portugal, Rio de Janeiro) -aʃku
• Hyphenation: as‧co

There are at least two hypotheses:

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

Compare Spanish asco.

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.
