I've been inventing languages for a long time. The first one happened after my first encounter with Latin. I was probably 14 or 15. I never really stopped, though there have been slow times when other things occupied my time. For example, work on Vaior, the only language of mine other people have tried to learn, pretty much stopped when I got focused on Ancient Greek. But even then, I might create a quick sketch of a language on a few scraps of paper while awaiting to be called for the tender ministrations of a dental hygienist.
Recently I've been involved in the community of people trying to learn Na'vi that exploded after the film Avatar came out. For the first time in my life I was seeing people eager to know about verb aspect and ejective consonants. I like to encourage that sort of thing, so I've been happy to help them. This has also resulted in me getting back to language invention of my own. Rather than fill my old blog, currently mostly devoted to ancient Greek, I decided to start a new blog just for my conlanging musings. Creating languages is a pretty obscure hobby, and not a populous one, but I hope there will be a few people who find my agonies of deciding between different ways to form relative clauses interesting or instructive (if only as a caution).
Right now, as I start this new blog, I have two quite different projects in development. The first, Bixwá, bears many signs of my recent attempt to learn an Athabascan language, Navajo, along with a few Algonquian touches. It is much further along, and right now is mostly in the arduous vocabulary-creation phase, though much syntactic fine-tuning remains. The second, Tsrai, is what happens when I decide to deliberately step away from old habits, with a little help from the WALS, and create a SVO language with no declensions and more features common across the world's languages.
From time to time I suppose I'll comment on the odd political or social developments among conlangers.
