from A plain English compound, exactly what it says: "sand" + "stone." "Sand" traces back to Old English sand, with relatives across the Germanic languages (German Sand, Dutch zand) and a deeper Indo-European root also lurking behind Greek and Latin words for sand. "Stone" comes from Old English stān, kin to German Stein. The pairing is the kind of honest, no-nonsense naming English does best — describing a thing by simply naming what it's made of.
