"having an air of distinction," 1813 (in Byron), from French distingué, literally "distinguished," past participle of distinguer "to separate between, keep separate, mark off" (see distinguish).
The girls I knew had sad and sullen gray faces
With distingué traces

By too many through the day
Twelve o'clock tales.

The Old Testament kine of Bashan, railed against in Amos 4:1-3 because they "oppress the poor," "crush the needy," and "say to their masters, Bring and let us drink," usually are said to be a figure for the voluptuous and luxuriously wanton women of Samaria, "though some scholars prefer to see this as a reference to the effeminate character of the wealthy rulers of the land" ["The K.J.V. Parallel Bible Commentary," 1994]. The word there translated Hebrew parah "cow, heifer." The cows of Bashan, east of the Sea of Galilee, grazed in lush pastures and were notably well-fed and strong beasts.
