I know it's a strange question, but how do I create a simplistic language? I mean I'm doing it for the book series that I'm about to start on and I need tips and/or possible help with how to develop a simplistic, but still very fleshed out language that some of the "races" in my story could speak (most of them are beast-races). I Mena I watched these videos to help me, but I seem to have trouble intermixing my lore with any possible language I could come up with.
Any advice?
