a word of well-known meaning, (Ṣ, L,) arabicized from [the Pers.] أُسْتُوِنْ [which signifies the same], (Ḳ,) i. q. سَارِيَةٌ [meaning A column, of stone or of baked bricks]: (Ṣ, M, L, Mṣb, Ḳ:) pl. أَسَاطِينُ (Ṣ, M, * L, Mṣb, Ḳ *) and أُسْطُوَانَاتٌ: (Mṣb:) it is of the measure أُفْعُوَالَةٌ, (Ṣ, L, Mṣb, Ḳ,) because its pl. is أَسَاطَينُ, the ن being radical, (L, Mṣb,) accord. to Kh (Mṣb) and Fr, who says that it is the only instance of this measure; (L;) or of the measure فُعْلُوَانَةٌ, (Ṣ, L, Ḳ,) accord. to Akh, but, (J says, L,) if so, the و is augmentative and has next to it two augmentative letters, and this is scarcely ever, or never, the case; (Ṣ, L;) IB, however, says that this is the true measure, as is shown by its pl., أَسَاطِينُ, and its dim.,
↓أُسَيْطِينَةٌ: (L:) accord. to some, it is of the measure أُفْعُلَانَةٌ, (Ṣ, L, Mṣb,) but, if it were so, it would not have for its pl. أَسَاطِينُ, as there is no instance of the measure أَفَاعِينُ. (Ṣ, L.)
[Also A portico. Hence, أَهْلُ الأُسْطُوَانَةِ The Stoics.
And A cylinder.]
And The legs of a beast: (Ḳ:) [or rather the pl.] أَسَاطِينُ has this meaning. (L.)
And The penis. (Ḳ.)
