cajón
/kaˈxon/ · B1 · noun · m
box
📦🥁 caja (box) + -ón (big) = a big box, or a box you slide in and out
The Spanish suffix -ón makes things bigger, so cajón is literally a big box. Caja comes from Latin capsa, the same root as English case and capsule. The Peruvian cajón drum is a wooden box you sit on and slap.
