And رَعَفَ أَنْفُهُ His nose bled; blood flowed from his nose: this is the chaste form of the verb: رُعِفَ, from which is formed the part. n. مَرْعُوفٌ, is incorrect; (Mgh;) unknown  to As: (O:) [or] رَعَفَ alone, aor. ـُ and رَعَفَ, has this last signification; as also رَعُفَ, (S, O, * Msb, K,) but this is a dial. var. of weak authority, (S, O,) or is rare; (Msb;) and رَعِفَ, aor. ـَ and رُعِفَ [mentioned above as incorrect]; (K;) and the inf. n. is رَعْفٌ (Msb, K) and رُعَافٌ, (K,) or the latter is a simple subst.

(KL.) b3:  And ارعف القِرْبَةَ He filled the skin (S, O, K) so that it overflowed (↓ حَتَّى تَرْعُفَ): (S, O:) whence the saying of a rájiz, ['Amr Ibn-Leja, so in a copy of the S,] أَعْلَاهَا مِنِ امْتِلَائِهَا ↓ يَرْعُفُ [Its upper part overflows, or overflowing, by reason of its fulness].
