For reasons not relevant to this post I was reading the wikipedia article on Brisbane, which noted, among other matters of interest, that the demonym, or preferred title, for a resident of Brisbane is a Brisbanite (preferred to the less popular Brisbanian).
I had never read or heard the word demonym before.
A person from Sydney is a Sydneysider; someone from Melbourne is a Melburnian (note the absence of the ‘o’); and a resident of Adelaide is an Adelaidian.
I think the local demonym is Mount Gambian in perference to Mount Gambierite.
If our town’s earlier name of ‘Gambierton’ had stuck we’d all have been Gambiertonites, which makes me think of ‘Chicken Tonight’ and everyone doing the Chicken Dance while singing ‘I am a Gambiertonite’, but now I’m rambling somewhat.
Anyhow, if you’re playing Scrabble and someone forms the word ‘demon’ and you’ve got a ‘y’ and an ‘m’, you know what to do.
We decided years ago that folk from OB Flat would Flatonians!
