In A Wizard of Earthsea, language is power. We don't mean that in some metaphorical way, like, if you're good with language, you can convince people to do what you want them to do. We mean that language is magical power: in order to cast a spell, you need to know the true names of things and you need to know how to speak the right language. But there's something odd about this. Language is usually a very social thing, right? It's something you use to talk to other people. But magical language is often a secret thing, with the wizards guarding their secret spells and everyone guarding their secret name.
