لُعَابٌ

What flows from the mouth; slaver; drivel. (S, K.)

[Mucilage of plants. See S, article لزج &c.]

لُعَابُ النَّخْلِ (tropical:) The honey of the date-palm. (S, K.)

لُعَابُ الشَّمْسِ (tropical:) A thing (that one sees, TA) as though descending from the sky, at the time of the mid-day heat; (K;) what one sees in a time of intense heat, resembling cobwebs: [i. e. gossamer:] also said to be the سَرَاب, or mirage: (S:) it is what is called مُخَاطُ الشَّيْطَانِ, and سَهَامٌ, and رِيقُ الشَّمْسِ, resembling threads, seen in the air when the heat is intense and the air calm: and he who asserts the لعاب الشمس to be the سراب says what is false; for that is the سراب that is seen at mid-day resembling running water: only he knows these things who has been constantly in the deserts, and has journeyed during the mid-day heats. (Az.) [In Egypt, in very hot and calm weather, I have seen, though very rarely, great quantities of the filmy substances above mentioned, resembling delicate and silky white cobwebs, generally of stringy forms, floating in the air.]
