To note an apparent oddity where this question is concerned:
He is a Spanish. - incorrect
He is Spanish. - correct
He is a Spaniard. - correct
It seems that other nationalities don't have a word like "Spaniard" in English.
1. I'm a Norwegian. - correct and it sounds "natural".
2. I'm a Chinese. - correct, but does it sound "natural"?
In light of sentence number 1, I can see Gwen's point about "He is a Chinese." quite clearly, yet at the same time, it just doesn't sound "natural" to me. It seems to be a rather odd inconsistency that I had never noticed before.
What about this one? - I'm a French. - I can't say it sounds quite right, yet "I'm a German." sounds fine to me.
"I'm a Swedish." Neither can I say this one sounds right. But this one, "I'm a Russian." sounds fine.
I'd have to say, though, that typically we would not use the indefinite article in this type of sentence.
Interesting inconsistencies we have here. mm....
