(TA.) طَلَّاسَةٌ A piece of rag with which one wipes a tablet (A, K, TA) upon which is writing, and with which the writing is obliterated, or effaced. (A, TA.) طَيْلَسٌ: see طَيْلَسَانٌ.طَالَسَانٌ: see طَيْلَسَانٌ.طَيْلَسَانٌ (El-Fárábee, S, M, Mgh, O, Msb, K) and طَيْلِسَانٌ, (M, O, K,) the latter form used by some, (El-Fárábee, Msb,) or by the vulgar, (S,) and disallowed by As, (M, Msb,) and طَيْلُسَانٌ, all these three forms being mentioned by 'Iyád and others, (K,) [accord. to the TA, following Lth; but the words of Lth, as cited in the TA, and in the O, rather signify that, if, instead of طَيْلِسَانٌ, with kesr to the ل, one said طَيْلُسَانٌ, with damm to the ل, like خَيْزُرَانٌ and حَيْسُمَانٌ, it would be more agreeable with analogy; and the like is said in the Msb, as on the authority of Az;] and ↓ طَيْلَسٌ (M, Mgh, O, K) and ↓ طَالَسَانٌ; (M, TA;) arabicized words, (S, Mgh, Msb, K,) from the Pers\., (S, Msb,) originally  تَالَسَانْ, (as in some copies of the K,) or تَالَشَانْ; (as in other copies of the K, and in some copies of the T, and thus written by El-Urmawee, as is said in the TA, and thus written also in the Mgh;) differently expl. by different persons; (TA;) [app. accord. to the fashions of different times and countries;] accord. to some, (TA,) A certain kind of كِسَآء: (M, TA:) or a certain article of apparel worn by the عَجَم [Persians or other foreigners], (Mgh, Msb,) of a round form, and black; accord. to the “ Jema et-Tefáreek,”having its woof and warp both of wool: (Mgh:) or a كِسَآء, of a dark, or an ashy, dust-colour, (أَخْضَر,) worn by persons of distinction: (EshShereeshee, in Har, p. 238:) [see also بَتٌّ, and سَاجٌ: El-Makreezee mentions a kind of طيلسان having a round piece cut out from the middle of it (مُقَوَّرٌ) worn by the Egyptian Wezeer, and called, in his time, (the 14th and 15th centuries of our era,) طَرْحَةٌ: (see this word: and see De Sacy's Chrest. Arabe, sec. ed., ii. 267—269; and Dozy's Dict. des Noms des Vêtements chez les Arabes, 278—90:) it seems to have resembled our academic hood, of which it was perhaps the original: the term طيلسان is now commonly applied to an oblong piece of drapery, or a scarf, or an oblong shawl, worn in such a manner that one end hangs down upon the side of the bosom, the middle part being turned over the head and under the chin, and the other end being thrown over the shoulder, and hanging down upon the back: this is worn by many of the professional learned men in winter, in Arabian countries: it is also used in the sense of the word عَذَبَةٌ, meaning an end of a turban, when made to hang down between the shoulders: see عَذَبٌ:] the pl. (of طَيْلَسَانٌ and طَيْلِسَانٌ and طَيْلَسٌ, M) is طَيَالِسَةٌ, (S, M, A, Mgh, Msb, K,) in which the ة is added because it is a foreign word, (S, M, K,) and طَيَالِسُ; (M, A;) or the latter is pl. of طَيْلَسٌ: (TA:) I do not know (says ISd) any  pl. of طَالَسَانٌ: (M, TA:) it is not allowable to form an abbreviation of طَيْلِسَانٌ, with kesr to the ل, as a compellation, because there is no instance of the measure فَيْعِلٌ, with kesr to the ع, except in infirm words such as سَيِّدٌ and مَيِّتٌ. (S.) Hence the expression, (Mgh,) يَا ابْنَ الطَّيْلَسَانِ, [lit., O son of the teylesán,] meaning, O 'Ajamee, (A, Mgh,) or Aajamee, (K,) [i. e., Persian, or foreigner,] used in reviling another; (Mgh, K;) for the عَجَم are those who [most commonly] attire themselves with the طيلسان.

(A.) b4:  A man having little hair upon the side of the cheek; pl. طُلْسٌ: or i. q. كَوْسَجٌ [q. v.]: of the the dial. of El-Yemen. (TA.) b5:  Dirty, or filthy; as also ↓ طِلْسٌ: (K:) the latter applied to a garment, or piece of cloth, (K, TA,) in the colour of which is a dusty hue: (TA:) and طَلْسَآءُ a dirty rag. (O.) b6:  A man (tropical:)  dirty, or filthy, in apparel: likened to a wolf in respect of the dusty hue of his clothes: (M:) or black and dirty. (O.) b7:  [Hence,] (assumed tropical:)  A man who is accused of foul, or evil, conduct; (Sh, O, K;) and so أَطْلَسُ الثَّوْبَيْنِ, an expression used by Ows Ibn-Hajar. (Sh, O.) b8:  (tropical:)  Black, as an Abyssinian and the like: (O, K:) as being likened in colour to a wolf. (TA.) [See also طَلْسٌ.] b9:  (tropical:)  A thief: (O, K:) because of his evil nature, (TA,) being likened to a wolf. (O, TA.) A2:  [Satin; so called in the present day;] a garment, or piece of cloth, of woven silk: [app. because of its smoothness:] but this is not [of the classical] Arabic: pl. طُلْسٌ. (TA.)
