I love languages, real or constructed. I'm a bit of a grammar nut--I'm much more likely to learn the grammar of a language, and leave behind the vocabulary. As a result, my constructed languages tend to have fairly simple phonological features, but full and robust grammars.
Right now, I'm working on Shabkiuza, a language that features in a book I've written. I started with just a few isolated phrases, but decided that it might be fun to build the whole thing. There are a handful of other languages in that universe too, and I look forward to building relationships between them.
