حِسْىٌ
1.
(T, S, K) and
حِسًى (Ahmad Ibn-Yahyà, AAF, K) and
حَسْىٌ, according to the K, but this is unknown, and the correct word is حَسًا, [or rather
حَسًى,] mentioned by IAar, (TA,) Water which the earth imbibes from sand [above it], and which, when it reaches what is hard, is arrested thereby: one digs out the sand from over it, and draws it forth: (S:) or accumulated sand, beneath which is hard rock, so that, when the sand is rained upon, it imbibes the water of the rain, which, reaching the rock beneath, is arrested thereby, and the sand prevents the heat of the sun from drying up the water; wherefore, when the heat is vehement, the upper portion of the sand is dug out from over the water, and it wells
forth, cold and sweet, and is taken by little and little: (Az, TA:) or soft, or plain, ground, in which water remains and collects: or rugged ground, over which is sand, that collects the rainwater; so that whenever a bucketful is drawn forth, another collects: (K, TA:) so in the M: (TA:) plural [of pauc.] أَحْسَاءٌ (S, K) and [of mult.] حِسَاءٌ: (K:) أَحْسَاءٌ is synonym with كِرَارٌ. (S.) [See also حَشْرَجٌ.]
