خَنْدَرِيسٌ Wine; (Ṣ, Ḳ;) so called because of its oldness: (Ṣ:) or old wine: (TA:) [accord. to some,] derived from خَدْرَسَةٌ, a word not explained: (Ḳ:) by some said to be of the measure فَنْعَلِيسٌ, so that its radical letters are خدر; because wine is مُخَدِّر [i. e. a cause of torpor or languor]: by some said to be from خَرْسٌ; but to this it is objected that د is not augmentative: the truth is, that it is of the measure فَعْلَلِيلٌ, as Sb says: (MF:) by the author of the L and others, it is mentioned after art. خنس: (TA:) or it is a Greek word, arabicized: (Ḳ:) [but I know not how this is, unless, as an epithet applied to wheat, (see what follows,) it be supposed to be from χόνδρος:] IDrd thought it to be an arabicized word: it may be an arabicized word from the Persian خَنْدَهْ رِيشْ, meaning “having a laughing beard,” [or rather “one whose beard is laughed at,” i. e., “a laughing-stock,”] because he who makes use of it [namely of wine] has his beard laughed at. (TA.)
