apropiado
/apɾoˈpjado/ · B1 · adj
appropriate, suitable
Cognate of English appropriate: from Latin ad + proprius, one's own
Latin proprius meant one's own, which is also the root of propio and property. Apropiado is something made properly one's own, so it fits. The English word appropriate is almost the same: drop the final -iate and add -iado.
