سبطرQ. 4 اِسْبَطَرَّ He stretched himself: (M:) he lay upon his side, and stretched himself. (S, K.) b2:  He (a slaughtered beast) stretched himself to die. (TA.) b3:  اسبطرّت الإِبِلُ فِى سَيْرِهَا The camels hastened, (M, * K, * TA,) and stretched themselves, in their march, or course. (TA.) b4:  اسبطرّت لَهُ البِلَادُ The provinces became rightly disposed to him. (Fr, K. *) سِبَطْرٌ A lion stretching himself when about to spring or leap. (S, K.) b2:  A quick camel: pl. سِبَطْرَاتٌ: it has no broken pl. (Sb, M.) b3:  Also, the pl. above mentioned, Camels long, upon the surface of the ground [or horizontally]. (S, K.) The ت [says J] is not the denotative of the fem. gender: (S:) it is like that in رِجَالَاتٌ (S, K) and حَمَّامَاتٌ, as masc. pls.: (S:) but IB says, the ت in this word is the denotative of the fem. gender; for it is an epithet applied to جِمَالٌ, which is fem. as a [broken] pl.; as is shown by the saying الجِمَالُ سَارَتْ, and رَعَتْ, &c.: and he adds, J's saying that it is like رجالات and حمّامات is a mistake, inasmuch as he confounds رجالات with حمّامات; for رِجَالٌ is a fem. pl., as is shown by one's saying الرِّجَالُ خَرَجَتْ, and سَارَتْ; but حَمَّامٌ is masc., and should not regularly have a pl. with ا and ت, but, as Sb says, it has this pl. form, like some other masc. words, in lieu of a broken pl., and would not have it if it had a broken pl. (TA.) b4:  Also the sing., Penetrating; effective; (Lth, M, K;) [as though stretching far;] sharp in intellect; clever; acute: (K: [in the CK, الماضِى السَّهْمِ is put by mistake for الماضى الشَّهْمُ:]) or sharp in intellect, and very bold or daring or courageous. (TA.) b5: Lank hair. (M.) b6:  A man (Sh) lank and tall. (Sh, K.) b7:  And with ة, A corpulent woman. (M.) سِبَطْرَى A proud and self-conceited gait, with an affected inclining of the body from side to side. (M, K.) سُبَاطِرٌ: see what next follows.سَبَيْطَرٌ and ↓ سُبَاطِرٌ Tall, or long. (M, K.) b2: Also the former, A certain bird having a very long neck, (S, K,) which one sees always in shallow water; surnamed أَبُو العَيْزَارِ. (S.)
