Unknown discovered alive and well in Penge!

I will have to think on this -- I'm sure that the grammatical mangling we Australians are so often accused of will provide an example or two.

"Mate" springs to mind immediately though. I can't strictly call it vocative-only, as it's quite the multipurpose word, but I don't know that it really works in the nominative.

Really, why do you make me do these things before coffee?

Hope your coffee has done its job. "Leanne's mate is a monk." There it is, prancing around in the Nominative!
