Root: ثعب
Full Definition
مَثْعَبٌ
[The outlet, or place of outpouring, of the water of a watering-trough &c.;] the place of passage for the water, in the side of a wateringtrough or tank: and a channel, or conduit, for water: pl. مَثَاعِبُ. You say مَثْعَبُ الحَوةَ [The outlet for the water of the watering-trough or tank]: and مَثْعَبُ السَّطْحِ [the outlet for the water of the house-top]: and مَثْعَبُ المَطَرِ [the outlet, or channel, for the rain-water]: from ثَعَبَ المَآءَ “he gave vent to the water,” or, “made it to flow forth,” &c. And مَثَاعِبُ المَدِينَةِ, meaning The channels, or places of flowing, of the water of the city: whence it appears that MF has erred in saying that مَثْعَبٌ signifies [only] a
مِزْرَاب [or spout for conveying away water from a housetop &c.]: not a channel, or place of flowing. [See also صُنْبُورٌ, and لَوْلَبْ.]
