بطح

أَبْطَحُ ذ , originally an epithet [and therefore imperfectly decl.], (M, TA,) that is, an epithet converted into a subst., and not used as an epithet, (Ham p. 21,) A wide water-course, or channel of a torrent, in which are fine, or minute, or broken, pebbles; (S, A, K, and Ham ubi suprà;) so called because the water goes in it to the right and left; [i. e. spreads widely; see 7;] (AA;) as also ↓ بَطْحَاآءُ, (S, A, K, Ham,) fem. of the former, and, like it, an epithet converted into a subst.; (Ham ubi suprà;) and ↓ بَطِيحَةٌ, (S, K,) and ↓ بَطِحٌ: (K:) or a water-course, or channel of a torrent, in which are sand and pebbles; as also ↓ بَطْحَاآءُ: (Mgh:) or a wide place [app. in a water-course ]; as also ↓ بطحة [app. بَطْحَةٌ, which is explained by Freytag, but without his stating on what authority, as signifying a depressed place through which water flows, abounding with pebbles; as is also بِطْحَةٌ; and in like manner Golius explains the former, but mentions the latter as a pl. of بطيحة]: (Msb:) or, accord. to AHn, the bottom of a water-course, or channel of a torrent, producing no plants or herbage: (TA:) or ↓ بَطْحَاآءُ signifies soft earth of a valley, such as has been drawn along by the torrents: (ISd, TA:) or the soft pebbles in the bottom of the water-course, or channel of a torrent, of a valley; as also أَبْطَحُ: (IAth, TA:) or the soft earth, such as has been drawn along by the torrents, in the bottom of a تَلْعَة [meaning a water-course &c.] and of a valley; and the أَبْطَح and ↓ بَطْحَاآء of a valley are its earth and soft pebbles: (En-Nadr, TA:) and accord. to AA, ↓ بَطِحٌ signifies sand in a بَطْحَاآء: (TA:) the pl. is أَبَاطِحُ and بِطَاحٌ (S, A, K) and بَطَائِحُ; (K;) the first of these, and the second also, contr. to analogy, being pls. of ابطح; (S;) or both are pls. of بطحاآء, contr. to analogy; (Ham p. 251;) or the first is pl. of ابطح, formed after the manner of the pl. of a subst. of this measure, though the sing. is originally an epithet; (M, TA;) and the second, as is asserted by more than one, is correctly pl. of بطحاآء, as is also بَطْحَاوَاتٌ; (TA;) and the third is pl. of بطيحة.
