سَمُومٌ
Root: سم
Full Definition
سَمُومٌ
, of the fem. gender, A hot wind, or, as some say, a cold wind, (M, [perhaps a mistake occasioned by a misunderstanding of the phrase سَمُومٌ بَارِدٌ, expl. below,]) in the night or in the day, or generally in the day, but authorities differ respecting it, as has been shown voce حَرُورٌ; accord. to AO, it is in the day, and sometimes in the night; and the حَرُور is in the night, and sometimes in the day: but some say that the former is in the night, and the latter in the day: [in the present day it is commonly applied to a violent and intensely-hot wind, generally occurring in the spring or summer, in Egypt and the Egyptian deserts usually proceeding from the south-east or south-south-east, gradually darkening the air to a deep purple hue, whether or not accompanied by clouds of dust or sand, and at length entirely concealing the sun; but seldom lasting more than about a quarter of an hour or twenty minutes:] the word is used as a subst. [i. e. alone], and also as an epithet [qualifying the subst. رِيحٌ]: pl. سَمَائِمٌ. One says also سَمُومٌ بَارِدٌ, meaning A
سَمُوم
that is constant, continual, permanent, settled, or incessant. (S and L in art. برد.) [See also بَارِحٌ.]
