رصف

رَصَفَةٌ ذ n. un. of رَصَفٌ, q. v. ― -b2- Also A sinew (عَقَبَةٌ) that is wound upon the socket of the head of an arrow, (S, M, O, K,) when it has broken; (M;) as also ↓ رُصَافَةٌ (Lth, O, K) and ↓ رُصُوفَةٌ, each with damm; (K;) or as also ↓ رِصَافَةٌ, [thus written with kesr,] of which the pl. is رَصَائِفُ (M) and [coll. gen. n.] ↓ رِصَافٌ; (M, O;) but [ISd says,] I think that AHn has made this last to be a sing.: and ↓ رَصَفٌ is the pl. of رَصَفَةٌ, [or rather it is a coll. gen. n.,] and أَرْصَافٌ I hold to be pl. of رَصَفٌ: (M:) or رِصَافٌ is the pl. of رَصَفَةٌ. (S, K.) ― -b3- Also, and ↓ رَصْفَةٌ, A sinew (عَقَبَةٌ) that is bound upon another sinew, and is then bound upon the suspensory (حِمَالَة) of the bow. (M.) ― -b4- And رَصَفَتَانِ [if not a mistake for رَضَفَتَانِ] Two round bones in the knee of a horse, separate from the other bones. (Ibn-'Abbád, O.
