قصب

قِصَابٌ ذ , (so in the K, there said to be like كِتَابٌ,) or ↓ قِصَابَةٌ, (so in the M and L,) A dam that is constructed in the place that has been eaten away by water, [for لَجْف in the CK, and لِحْف in other copies of the K, (in the place of which I find لُهْج in a copy of the M, app. a mistranscription,) I read, and thus render لَجَف, supposing it to mean such a place in the side of a rivulet for irrigation, ] lest the torrent should collect itself together from every place, and consequently the border of the rivulet for irrigation of the garden of palm-trees [thus I render عِرَاقُ الحَائِطِ (see art. عرق)] should become demolished. (M, K.) ― -b2- And قِصَابٌ signifies دِبَارٌ: (so accord. to a copy of the M:) or دِيَارٌ: (so in copies of the K:) [the former I think to be the preferable reading; but its meaning is doubtful: accord. to the K it signifies Small channels for irrigation between tracts of seed-produce; and ISd says the like: accord. to AHn, patches of sown ground: see more voce دَبْرٌ: it is a pl.,] and the sing. is ↓ قَصَبَةٌ. (M, K.)
