Anyone who knows me could tell you I'm a HUGE language nerd. When I wrote "The Aetherverse," I decided to take being a polyglot to the next level and invented a series of constructed languages (or conlangs) for the galaxy's most prominent civilizations. You can do the same for your sci-fi or fantasy story, even if you don't have a formal background in linguistics.
