جَرٌّ
1.
(tropical:) The foot, bottom, base, or lowest part, of a mountain; (S, A, K;) like ذَيْلٌ: (A, TA:) or the place where it rises from the plain to the rugged part: (IDrd, TA:) or الجّرُّ أَصْلُ الجَبَلِ is a mistranscription of Fr, and is correctly الجُرَاصِلُ الجَبَلُ [i. e. جُراصِلٌ signifies “a mountain”]: (K:) but جُرَاصِلٌ is not mentioned [elsewhere] in the K, nor by any one of the writers on strange words; and [SM says,] there is evidently no mistranscription: جَرُّ الجَبَلِ occurs in a tradition, meaning the foot, &c., of the mountain: and its plural is جِرَارٌ. (TA.)
