Origin & History of “sand”
Sand is a widespread Germanic word, shared by German, Swedish, and Danish (Dutch has zand). Its prehistoric source was *sandam, which went back to an Indo-European *samdam. this also produced Latin sabulum ‘sand’, which evolved into French sable and Italian sabbia ‘sand’. It probably came ultimately from a base which signified ‘grind, crush’.
