embajador
/embaxaˈdoɾ/ · B1 · noun · m
ambassador
🏛️🤝 embajada (embassy) + -dor (the one who does) = the embassy's person
Spanish -dor marks the doer, as in jugador (player) and trabajador (worker). Embajador and English ambassador share one root: Latin ambactus, servant or envoy. Swap the am- for em- and the -ss- for -j- and you have the Spanish word.
