Hah, I was about to ask the exact same thing.Mace Panda Poo wrote:When you say "USian", do you pronounce it "you-es-ian" or "you-sian"; i hope you can understand the sounds i'm trying to type.
Regarding 'American', I've conveniently aligned myself with the masses and take the word to mean 'resident of the USA' unless context implies otherwise. If we're talking about the origin of tobacco, I'd take American to mean 'from the Americas', though if someone introduces themselves as American I certainly wouldn't think they're from Chile.
If I was pressed to justify the above, I'd probably say that technically there's no continent called America, and therefore the word is unambiguous and equivalent to the USA.
