لب

لَوْلَبٌ ذ A large quantity of water, which, when the aperture (مَفْتَح, as in the T; or فَتْح, as in MS. copies of the K; in the CK فُتُح;) [mean- ing the aperture of the tank or the like] carries off thereof what it can, and the hole by which it runs out (صُنْبُورُهُ, meaning the مَثْعَب of the water, TA,) is too narrow to admit it freely on account of its abundance, whirls round, and becomes like the spout of a vessel. (T, K.) AM says, I know not whether it be an Arabic word or arabicized; but the people of El-'Irák are fond of using it. (TA.) [It appears to be from the Persian لُولَهْ, as Golius thinks; and is used in modern Arabic in several other senses; namely, A tube through which water flows: the spout of a ewer, of an alembic, and the like: a cock, or tap: a turning pin, or peg; a screw: and the like. Its more appropriate place, I think, would be in an art. composed of the letters للب (accord. to what is said of مُلَوْلَبٌ in the S, K); or rather, (accord. to its derivation from the Pers.,) لولب.] Pl. لَوَالِبُ. (TA.)
