Etymology
The word "blue" traces back to Old English blǣwen (a derivative of blǣw, meaning "blue dye"), which itself stems from Proto-Germanic blēwaz. This root is shared with other Germanic languages (e.g., German blau, Dutch blauw). The color association is ancient, but the emotional sense ("sad") emerged in the 19th century, likely influenced by phrases like "the blues" in music.
