ᏣᎳᎩᏍ ᎯᏬᏂᏍᎩ?

I don't. Not really. But the cherokee syllabary (see, I caught on to the correct spelling!) is used in a lot of sign-age in some states!

The only problem I have with using that (or a similar system) is that the *written* language wasn't developed at all until around the 1800s (pretty sure) so it was a late entry... my stories usually start much earlier in history... with early writings.
It's so beautiful though...
So... do you just adapt the lettering from that to your own system? It looks great.

Is the "-M" to indicate that can only come before one of your "M" syllables? Like how q (usually) can only come before a "u" in english? :s

Or is it a different sound altogether?

I don't understand the notation.
