Can any nationality be expressed by adding + jin to the country name?


So, many country nationalities are written by adding +jin to the country name
like Itaria-jin イタリア人 , Oranda-jin オランダ人, Kanada-jin カナダ人, Supein-jin スペイン人 ,
etc.

but there are some like american who can be written 米国人 Beikokujin or アメリカ人
Amerikajin.

And some others you only commonly find it with an original name like ドイツ人
Doitsujin or 中国人 Chūgokujin. How about countries like these last ones. Can
they also be written country name + jin or it's only valid to call them with
their original names?




Your understanding is halfway correct. But, your last paragraph is a little
misguided.

German people in Japanese are described as ドイツ人 because Germany is ドイツ from
_Deutschland_ , which is the German word for Germany.

Chinese people are 中国人 because China is 中国｛ちゅうごく｝, which is the Japanese
音読{おんよ}み rendering of the Kanji for China (中国 or 中國, if traditional Kanji are
employed).

(The United States of) America can be represented with two words: the loan
word アメリカ, or the 音読み-derived reading of 米国. アメリカ is obvious, but 米国 exists
because of the 当｛あ｝て字｛じ｝ for rendering the word America: 亜米利加. The 米 was
preserved to make the word 米国, which also means America.

Therefore, whether you use アメリカ人 or 米国人, it is still the same pattern.

That means that, just like the other groups you mentioned, they all follow the
pattern:

> _country + 人_
