Talk:R'lyehian
No offense but have you taken into acount the probablity that not every word in these authers stories may be of the same language. In Through the Gates of the Silver Lovecraft mentions Hyoerborean Tsath-Yo and R'lyeh Glyphs. In Out of Aeons he mentions Muvian Naacal. Arthur Machen's Aklo language allso turns up in several stories.
Plus many of the words used in spells and rituals may be incantatory words with no actuel liguistic meaning.
