سندسسُنْدُسٌ Thin, or fine, دِيبَاج [or silk brocade]: (Th, M, Bd and Jel in xviii. 30, Jel in xliv. 53, Msb, K, TA:) or thin, or fine, حَرِير [q. v.]: (Bd in xliv.:) opposed to إِسْتَبْرَقٌ: (TA:) or i. q.  بِزْيَوْنٌ [expl. by IB as meaning thin, or fine, ديباج: so in the TA in art. بزن]: (S:) or a kind of بزيون; (Lth, K, TA;) made of [the kind of down called] مِرْعِزَّى: (Lth, TA:) or a kind of بُرُود [pl. of بُرْدٌ, q. v.]: (M, K:) [accord. to Golius, præstans et subtile panni serici genus; as on the authority of Ibn-Maaroof: and Attalicus pannus, aurum argentumve intextum habens; as on the authority of J, who, however, explains it only by the word بِزْيَوْنٌ: it is mentioned in the S and Msb in art. سدس; and in the latter, is said to be of the measure فُنْعُلٌ; but accord. to the K, the ن is a radical letter:] it is [said to be] an arabicized word, without contradiction, (Lth, K,) as well as إِسْتَبْرَقٌ: (Lth:) but both these words occur in the Kur-án, and Esh-Sháfi'ee and others deny that any arabicized word occurs therein: [though they are opposed by Bd (xvii. 37) and others:] some say that they are instances of the agreement of different languages.
