رصف

رَصَفٌ ذ Stones put, or joined, together, (S, M, O, Msb, K,) [ whether artificially or naturally, and particularly] in a channel of water: (O, K:) n. un. ↓ رَصَفَةٌ. (S, M, O, Msb, K.) A dam constructed for [ the purpose of obstructing or retaining ] water: [such is now termed ↓ رَصِيفٌ; which is originally an epithet, but thus used as a subst., and commonly applied to a quay; and a bank, generally of masonry or bricks, raised along the side of a river or of a lake &c.; and any similar mass of masonry: ] also (i. e. رَصَفٌ) the channel of a [ reservoir such as is termed ] مَصْنَعَة. (M.) [Hence,] مَاآءُ الرَّصَفِ The water descending from the mountains, upon the rocks. (K.) El-'Ajjáj says, مِنْ رَصَفٍ نَازَعَ سَيْلًا رَصَفَا meaning that the wine of which he is speaking was mixed with water of a رَصَف [or ledge of rocks or stones ] that had contended, in flowing, with another رَصَف, because of its thereby becoming more clear and more delicate: he suppresses the word signifying water, meaning it to be understood, (saying مِنْ رَصَفٍ for مِنْ مَاآءِ رَصَفٍ, [but in both of my copies of the S, مَاآءٍ is erroneously put for مَاآءِ,]) and he calls its passing (مَسِيرَهُ [in the O and in one of my copies of the S مَسيلَهُ]) from رصف to رصف its contending therewith [i. e. with the latter رصف]. (S, O.) ― -b2- See also رَصَفَةٌ.
