مَرْكُوٌّ
1.
[pass. particle n. of 1:
2.
and hence, as a subst.,] A large watering-trough or tank: (AA, T, S, K:) [in the S and K is added, وَالجُرْمُوزُ الصَّغِيرُ, which may mean either that the small watering- trough is called جرموز, and such is the case, or that مَرْكُوٌّ also signifies a small
جرموز, agreeably with what here follows, and with an explanation of this word in the TA voce حَوِىٌّ:] Az, after mentioning AA's explanation given above, says, but what I have heard from the Arabs is, that the مركوّ is a small watering-trough or tank, which a man makes, or forms, or fashions, in a suitable manner, with his hands, at the head of the well, when he has not, and cannot procure, a vessel in which to give water to a camel or to two camels: and that which is large is not thus called. (TA.) [But see an example voce سَلْسٌ.]
