Recently a friend asked me what people who live in Atlanta call themselves. I felt a little off-guard when I answered, "Well, Atlantans, I guess." I know I've used that moniker for years, but never very consciously.
As it turns out, terms for people who live in certain localities are called "demonyms." Demonyms are usually just a matter of adding a suffix such as -ite, -an, -ian, or -er to the end of the place name. Some examples are Seattleite (I love that one!), Ottawan, Californian, and Londoner.
There is also -ese, as in Taiwanese, -ish, as in Irish, -i, as in Iraqi, and -ine, as in Argentine.
There are less common suffixes, too, such as in the Glaswegian from Glasgow, the Oslovian from Oslo, the Spaniard from Spain, and the Slovenes from Slovinia.
Then there are the names were nothing is added, but taken away. Afghans, Croats, and Thai live in Afghanistan, Croatia and Thailand.
Some of these don't even make much sense (at least to me.) For example, folks from Manchester are called Mancunians. Wha? And then how do you even make a name for denizens of Massachusetts? (Turns out they are Bay-Staters).
We in Portland, OR are Portlanders. I work with a bunch of Vancouverites in Washington. I have been, at different points in my life, a Missourian (often pronounced Missouran), a Louisianian, a Tennesseean, and a Georgian. I am engaged to a Texan.
So are you Saranacians? Saranac Lakers? Sarcusians? Please enlighten your fellow earthlings!
In the meantime, here are some books on demonyms:
