+1 more sourceA clamp is basically a handshake with a vice-grip. English seems to have picked it up around 1300 from Middle Dutch, where clamp and klampe were the sort of hard, practical words you’d expect around docks, workshops, and stonecutters’ yards. But the family goes deeper: Old English already had clamm, meaning a bond or fetter, so the idea of something pinning, gripping, or binding was already wandering around the language waiting for a better tool. That same grim little Germanic cluster turns up in words for cramp, clasp, and even harpoon-adjacent tools like the Old French harpon, where the whole point is to snag and hold. So when you clamp two boards together, you’re using a word that has been obsessed for a thousand years with one thing: no escape.
