It's a functioning language in that I have developed a basic grammar and syntax, and have a vocabulary list which I have devised, some from Gaelic of course, but from languages less often used. Russian, Arabic, Chinese, Japanese. I try to follow these rules that I've set up but occasionally I realize I have to invent a new rule because I'm doing something I've never done before but it all follows the grammar I've devised. As far as the Aiel that I've devised as a culture they have bits of Apache, bits of Bedouin, bits that are simply mine.
