alteza
/alˈteθa/ · B1 · noun · f
highness
👑📏 alto (high) + -eza (-ness) = highness, height
Spanish -eza turns adjectives into nouns, like English -ness: belleza is beauty, tristeza is sadness. Add it to alto (tall, high) and you get alteza: height, stature, and the royal title Su Alteza, Your Highness.
