brume f (plural brumes)[1]

Etymology

It is borrowed from Old Occitan bruma according to Bloch and Wartburg and the Grand Robert, the regular outcome of Latin brūma (“winter solstice, winter”).[2][3][4] Rey and Wiktionary instead take it straight from Latin, with the Old Occitan word as a very possible intermediary.[5][1] Bloch and Wartburg point to the word's rarity in Old French and in the northern dialects as the reason to see it as a loan from the south.[2] The Latin word first meant the shortest day of the year, the winter solstice, and then, in poetry, the cold season.[5][6] Rey thinks it is probably the feminine, used as a noun, of an old superlative *brevima of brevis (“short”), as Varro's explanation of the name already suggests.[5][7]

Cognate with Italian bruma (“winter”), Spanish bruma (“mist”), Portuguese bruma, Catalan broma and Romanian brumă (“hoarfrost”).[2][8][9]

Earliest recorded meaning

Borrowed in 1265, it named the period of the shortest days, that is, winter.[5][3] Rabelais in the 16th century still writes that there is never a storm at sea sept jours devant et sept jours après brume “seven days before and seven days after the winter solstice”.[8]

Semantic evolution

The sense “winter” lost ground to hiver, which finally drove it out.[5] Because the season was marked by its weather, the word moved to “fog at sea” (1562), a seaman's use that spread at the end of the 17th century;[5][3] Furetière's dictionary of 1701 records it.[5][3] In 1752 it was used more widely for the haze of fine droplets that forms over water, and then for a thin veil of fog in general.[5]

After 1850 it took the figurative sense of anything that keeps one from seeing or understanding clearly.[5][7] The word only became common in the 18th century, and its lasting derivatives date from then: brumeux (1787) and brumaire (1793), the month of fog in the Revolutionary calendar.[5][2] English borrowed it as brume “fog, mist” in 1808.[10]
