A thick mist, fog, or haze, especially one that obscures visibility and creates a gloomy atmosphere.
From French brume meaning 'mist' or 'fog,' derived from Latin bruma meaning 'winter' or 'winter solstice,' referencing the foggy season; the word entered English in the 16th century.
The word brume connects to brumalia through the same Latin root—both reference the cold, dark season when winter fog rolls in, which is why ancient Romans associated this time with Saturn and mystery.
