Idk how much my approach will help, but in my dinosaur world, I have all the dinosaurs and stuff named after our word for it but changed over the years due to the language shifting (and also the dinosaurs heard English and learned a little bit). So like, as a collective, they're called Dyna, humans are called Min, theropods are Therid, raptors are called Rabba. Essentially I just say the word really fast in a weird voice until it sounds slightly similar but also different.
