"bucket," late Old English scutel "dish, platter," from Latin scutella "serving platter" (source also of French écuelle, Spanish escudilla, Italian scudella "a plate, bowl"), diminutive of scutra "flat tray, dish," perhaps related to scutum "shield" (see escutcheon).
A common Germanic borrowing from Latin (Old Norse skutill, Middle Dutch schotel, Old High German scuzzila, German Schüssel "a dish"). Meaning "basket for sifting grain" is attested from mid-14c.; sense of "bucket for holding coal" first recorded 1849.
