بلق

أَبْلَقُ ذ , applied to a horse, fem. بَلْقَاآءُ, Black and white: (S, K:) or white in the hind legs as high as the thighs: (ISd, K:) pl. بُلْقٌ: which is applied by Ru-beh to mountains: but the Arabs apply the epithet ابلق to a beast of the equine kind, and أَبْرَقُ to a mountain (TA) and to a sheep or goat: (Lh, TA in art. برق:) the former is also applied to a rope. (JK.) طَلَبَ الأَبْلَقَ العَقُوقَ (which is a prov., TA) means He sought an impossible thing; because ابلق is applied to a male, and عقوق means pregnant: or الابلق العقوق means the dawn; because it breaks, (lit., cleaves,) from عَقَّهُ signifying شَقَّهُ. (K.)
