Re: Alien Language Vs Not Very Alien Language
For sounds, maybe find a related collection of noises and approximate them with speech sounds/letters. Bird calls, mechanical sounds, musical instruments; some collection that you can intuitively relate as a set but are at different angles from normal human speech.
Kind depends on the aliens, I suppose, but what if alien "names" don't work like ours? Maybe each alien has a collection of names, each to be used only in its proper context?
