(S, M, K.) سِرْوَالٌ: see سَرَاوِيل, latter half, in two places.سِرْوِيلٌ: see سَرَاوِيل, in the latter half.سِرْوَالَةٌ: see the next paragraph, latter half, in two places.سَرَاوِيل a Pers\. word, (S, * M, Msb, * K,) originally شَلْوَار, (MA, KL, [in the former loosely expl. by the word إِزَارٌ, and so in the PS,]) of well-known meaning, (S,) [Drawers, trousers, or breeches; originally applied to such as are worn under other clothing;] a certain under-garment; (MA;) [but now applied also to such as are worn externally;] is masc. [and perfectly decl., i. e. with tenween], and fem. [and imperfectly decl., i. e. without tenween]; (S, M, Msb, K; *) sometimes  masc., (Msb, K,) but not known to As otherwise than as fem.; (M;) accord. to the usage most commonly obtaining, it is imperfectly decl. and fem.: (MF:) Sb says that it is a sing., and is a foreign, or Pers\., word, arabicized; resembling, in their [the Arabs'] language, what is imperfectly decl. [as a pl. of the measure فَعَالِيلُ] when  determinate and when indeterminate; but is perfectly decl. when indeterminate; and imperfectly decl. if applied as a proper name to a man, and so is its dim. if so applied, because it is fem. and of more than three letters: (S:) or it is imperfectly decl. as a proper name because it is also originally a foreign word; and its dim., ↓ سُرَيْيِيل, [for سُرَيْوِيل, the و being changed into ى, as in سَيِّدٌ for سَيْوِدٌ,] is perfectly decl. unless used as a proper name, in which latter case it is imperfectly decl. [for the reason above mentioned or] because it is fem. and determinate: (IB, TA:) it (i. e. سَرَاوِيل) is made, as a pl., imperfectly decl. when  indeterminate by some of the grammarians; (S;) and it occurs in poetry imperfectly decl. [when indeterminate]: (S, M, * IB, TA:) [but this may be by poetic license:] thus in the saying of Ibn-Mukbil, أَتَى دُونَهَا ذَبُّ الرِّيَادِ كَأَنَّهُ فَتًى فَارِسِىٌّ سَرَاوِيلَ رَامِحُ [The came as an obstacle intervening in the way to her, or them, the wild bull, as though he were a Persian youth in drawers; one with a pair of horns]: (S, * IB, TA:) the former [however] is the usual way, [contrary to what has been said on the authority of MF,] though the latter is more valid: (S:) the pl. is سَرَاوِيلَاتٌ: (S, M, Msb, K:) Sb says that it has no broken pl., because, if it had, it would be the same as the sing.: (M:) or, (K,) some say, (S, M, Msb,) namely those grammarians who make it imperfectly decl. when indeterminate, (S,) holding it to be [originally] an Arabic word, (Msb,) it is a pl. of which the sing. is ↓ سِرْوَالَةٌ (S, M, Msb, K) and ↓ سِرْوَالٌ (S, K) and ↓ سِرْوِيلٌ, which is [said to be] the only instance of a word of the measure فَعْوِيلٌ: (K:) [this, therefore, confirms the opinion that I hold, that the measure of this word is فِعْلِيلٌ, and that all the words of the present art. are quadriliteral-radical, agreeably with an assertion in the TA that سرل is not genuine Arabic: though it seems that all the lexicographers regard the و in the words of this art. as augmentative:] a poet says, فَلَيْسَ يَرِقُّ لِمُسْتَعْطِفِ * ↓ عَلَيْهِ مِنَ اللُّؤْمِ سِرْوَالَةٌ [Upon him is an under-garment of ignobleness, (i. e. ignobleness cleaves to him like a pair of drawers,) so that he does not become tenderhearted to one who endeavours to conciliate him]: (S, * M:) in the “ Mujarrad,” سَرَاوِيلُ is made fem., and ↓ سِرْوَالٌ masc.: (Msb:) سَرَاوِين is a dial. var.; (K;) or syn. with سَرَاوِيل; the ن in the former being asserted by Yaakoob to be a substitute for the ل [in the latter]: (M:) and شِرْوَالٌ, with ش, is likewise a dial. var. [of سِرْوَالٌ], (K,) mentioned by Es-Sijistánee, on the authority of some one or more of the Arabs: (TA:) [the common modern pronunciation is شَرْوَال: pl. شَرَاوِيل.]سُرَيْيِيل: dim. of سَرَاوِيل, q. v. (IB, TA.) مُسَرْوَلٌ Clad with سَرَاوِيل; as also ↓ مُتَسَرْوِلٌ. (A, TA.) b2:  [Hence,] طَائِرٌ مُسَرْوَلٌ (tropical:)  A bird whose plumage clothes its legs. (M, L, TA.) and حَمَامَةٌ مُسَرْوَلَةٌ (tropical:)  A pigeon having feathers upon its legs. (S, K, TA.) And فَرَسٌ مُسَرْوَلٌ, (K,) or فَرَسٌ أَبْلَقُ مُسَرْوَلٌ, (A'Obeyd, S, TA,) (tropical:)  [A horse, or a black and white horse,] whose whiteness of the legs extends (A'Obeyd, S, K) beyond, (A'Obeyd, K, TA,) or to, (S,) the arms and thighs: (A'Obeyd, S, K:) or مُسَرْوَلٌ applied to a horse means white in the hinder part, [and black, or of some other colour, in the hind legs,] the whiteness descending to the thighs. (A, voce آزَرُ.) b3:  And المُسَرْوَلُ signifies (assumed tropical:)  The wild bull: because of the blackness that is in his legs. (Az, TA.) مُتَسَرْوِلٌ: see the next preceding paragraph.
