caja

box, case; bank; cash desk; cash register, register, cash box; gearbox

Probably borrowed from Catalan caixa or Occitan caissa, from Latin capsa. (Latin /-ps-/ yields palatal outcomes in the latter two, but not in Spanish; cf. Latin ipse > Spanish ese, Catalan eixe.) Related to English case and cash and, more distantly, Spanish quijada. Cognate with Asturian and Aragonese caxa (“box”), French caisse (“box”), châsse (“case, reliquary”), Galician, Mirandese, and Portuguese caixa (“box”), Italian cassa (“case”), Leonese caixa, caxa (“box”).
