Language doesn’t stand still, not even the fusty old English language. Right now it seems in the throes of some kind of seismic shift, getting freaky with hash tags and acronyms. It seems likely that a hundred years from now, whatever’s being spoken and ”written” around these parts won’t look a hell of a lot like what we have now. Which is why it’s also worth reflecting, on International Mother Language Day, that Australia is the custodian of the oldest known languages on earth. And that most of them are endangered.
