clean (English)
Where does "clean" come from?
The word 'clean' descends from the Old English 'clǣne' and the Proto-West Germanic '*klainī', which originally described something 'shining', 'fine', or 'splendid'. These roots trace back to the Proto-Indo-European '*gel-', meaning 'to gleam'. Over centuries, the meaning shifted from a broad sense of physical brightness or fineness to the modern concept of being free from dirt, impurities, or moral corruption.
