Does anyone know what the heck KLEX is referring to in the Wikipedia articles on Tlingit? It appears to mean a "ka" particle that shows up now and then, but I can't find any information online about what this KLEX might mean. The articles don't explain. It looks like it might mean "k-lexifier", but that's a rather unhelpful term if it is.
Thanks for any help, especially if you know what the KLEX is used for in Tlingit
