A Finn is a person from Finland. Write it with a capital F when it means that. The adjective and the language are Finnish, not Finn: you can say “She is a Finn” or “She is Finnish,” but “Finn language” is not how people say it.

A Finn芬蘭人 is a person from Finland指來自芬蘭的人。Write it with a capital F這個意思要大寫F when it means that才對。The adjective and the language形容詞和語言 are Finnish, not Finn是 Finnish，不是 Finn: you你 can say "She is a Finn" or "She is Finnish,"可以說「She is a Finn」或「She is Finnish」, but "Finn language"不過「Finn language」 is not how people say it不是大家的說法

Though actually, the old northern word behind Finn did not start as a neat label for today’s country. In Old English the Finnas were people of the far north, and the name was used for the Sami; the Old Norse word finnr may first have meant a hunter-gatherer, perhaps a ‘finder’ of food. The country name Finland kept that old word.

Though actually不過其實, the old northern word behind Finn這個字背後古老的北方詞 did not start as a neat label for today's country一開始並不是為今天這個國家量身打造的整齊標籤。In Old English在古英文裡 the Finnas「Finnas」 were people of the far north指的是極北方的民族, and the name這個名稱 was used for the Sami也用來指薩米人; the Old Norse word finnr古諾斯語的 finnr may first have meant a hunter-gatherer最早可能指的是狩獵採集者, perhaps a 'finder' of food或許是食物的「尋找者」。The country name Finland國名 Finland kept that old word就是保留了這個古老的字

You do not need this history to use Finn correctly now — it just means someone from Finland — but it is why the tidy modern map and the old word do not match perfectly.

You你 do not need this history to use Finn correctly now不需要知道這段歷史也能正確使用 Finn — it它 just means someone from Finland就是指來自芬蘭的人 — but it is why不過這就是為什麼 the tidy modern map and the old word do not match perfectly整齊的現代地圖和這個古字對不太起來的原因

Separately, Finn is also a given name (from Irish Fionn, “fair”). That name is a different story; do not mix the two origins.

Separately另外, Finn Finn 也 is also a given name也是一個名字（from Irish Fionn, "fair"來自愛爾蘭語 Fionn，意思是「白皙／公平」）。That name這個名字 is a different story是另一回事; do not mix the two origins不要把這兩個來源搞混
