Forms

humo m (plural humos)[1] Old Spanish wrote fumo;[2][3] Galician and Old Leonese have fume.[2][3]

Etymology

It is inherited from Old Spanish fumo, inherited from Latin fūmus (“smoke”).[2][4][5][1] The same word is common to all the Romance languages: Portuguese fumo, Galician fume, Catalan fum, Occitan fum, Italian fumo and Romanian fum, with Aranese ⟨hum⟩.[2][3][6] Judeo-Spanish has Ladino umo.[1] The spelling with ⟨h⟩ replaced ⟨f⟩ later: the DTME dates ⟨fumo⟩ from 1087 and ⟨humo⟩ from 1337.[7]

The Latin word goes back to Proto-Italic *fūmos and Proto-Indo-European *dʰuh₂mós (“smoke”).[1][8] Its cognates are Sanskrit धूम (dhūmá, “smoke”), θυμός (thūmós, “spirit”), Lithuanian dū́mai, Old Church Slavonic дꙑмъ (dymŭ) and Old High German toum (“steam”).[8][1] De Vaan cites Schrijver's explanation of the long ⟨ū⟩ of Latin, where a shortened vowel would be expected, as analogy with fūlīgō (“soot”) and suffiō.[8]

Earliest recorded meaning

The DCECH's first record is fumo in a charter of 1088, followed by Berceo and the Libro de Alexandre.[2][4] The earliest literary hit in the CDH is the Fazienda de Ultra Mar (c. 1200, in a 13th-century copy): “alço so fumo como fumo de fornaz” “its smoke rose like the smoke of a furnace”.[9] Berceo, in Del sacrificio de la misa, describes the censer that “dava más dulz fumo que un dulz lectüario” “gave smoke sweeter than a sweet electuary”.[9]

Semantic evolution

Besides the smoke of a fire, the word named the vapour of anything fermenting, and by the 18th century the households of a village, counted by their hearths, a use Covarrubias had already recorded.[10] Medieval Latin fumus had the same sense “household”.[11] Autoridades also lists humo as a thin black silk worn for mourning.[10] Terreros (18th century) used it for anything vain and empty, and the plural humos “vanity, conceit” was in the Academy's dictionary by 1843, with vender humos “to boast of influence with the powerful” and a humo de pajas “lightly, without purpose”.[12][13] The last phrase occurs in Quito in 1560.[14] Bajarle a uno los humos “to take someone down a peg” is in the Academy's dictionary of 1884.[15]

In Argentina hacerse humo means “to vanish”, and írsele al humo a uno “to go straight at someone”.[16] In Mexico and Cuba humo names several leguminous trees, and in Cuba it meant drunkenness.[16][17] The popular derivatives have ⟨h⟩ (humear, ahumar), while fumar, fumigar and esfumar were taken later from French, Latin and Italian.[2][4]
