Think about it. What is a language, exactly? It’s not just how to make sounds with your voice…The language downloader really is so much more than its name implies.
If you really think about it, you’ll realize that a language is a conceptual framework. You can’t speak to someone, either vocally or telepathically, unless you both have the same understanding of the underlying concepts beneath the words. Making the right sounds doesn’t mean a thing if you can’t understand the concepts the words are meant to convey.
This is why you can clearly hear, and even repeat in an articulate matter, the words your doctor or lawyer says, but if you’ve not studied medicine or law, have no idea what they are talking about. You don’t know the language of medicine or law, the conceptual framework those disciplines are based upon.
