Words related to haze
"weather condition consisting of a cloud resting upon the ground, fog," also "precipitation consisting of fine droplets of water, much smaller than rain," Old English mist (earliest in compounds, such as misthleoðu "misty cliffs," wælmist "mist of death"), from Proto-Germanic *mikhstaz (source also of Middle Low German mist, Dutch mist, Icelandic mistur, Norwegian and Swedish mist), perhaps from PIE *meigh- "to urinate." Greek omikhle "fog;" Old Church Slavonic migla"fog;" Sanskrit mih- "fog, mist," megha "cloud" sometimes are said to be cognates in this secondary sense, but Beekes finds these rather more likely to be from a separate IE root meaning "fog."
Sometimes distinguished from fog, either as being less opaque or as consisting of drops large enough to have a perceptible downward motion. [OED]
Also in Old English in reference to dimness of the eyes or eyesight, either by illness or tears, and in a figurative sense of "something that darkens and obscures mental vision." Meaning "haze of dust in the air producing obscurity of things seen at a distance" is by 1785.
"brutal initiation, act of abusing a newcomer," 1848, said to be a college word ("This word is used at Harvard College, to express the treatment which Freshmen sometimes receive from the higher classes, and especially from the Sophomores" -- "Collection of College Words and Customs," Boston, 1851), but perhaps originally nautical; see haze (v.).
The thing is older than the word. Compare pennalism "exceptional tyrannical hazing of college freshmen by older students at 17c. German Protestant universities," from German pennal (from Latin) "a pen-case;" also "a freshman," so called for the cases they dutifully carried to lectures.
1905, blend of smoke and fog, formed "after Lewis Carrol's example" [Klein; see portmanteau]. Reputedly coined in reference to London, and first attested there in a paper read by Dr. H.A. des Voeux, treasurer of the Coal Smoke Abatement Society, though he seems not to have claimed credit for coining it.
At a recent health congress in London, a member used a new term to indicate a frequent London condition, the black fog, which is not unknown in other large cities and which has been the cause of a great deal of bad language in the past. The word thus coined is a contraction of smoke fog "smog" — and its introduction was received with applause as being eminently expressive and appropriate. It is not exactly a pretty word, but it fits very well the thing it represents, and it has only to become known to be popular. [Journal of the American Medical Association, Aug. 26, 1905]
Smaze (with haze (n.)) is from 1953.
