köken: Borrowed and first attested in the 16th century Dutch translation of Olaus Magnus Historia de Gentibus Septentrionalibus by Cornelius Grapheus, but whether it was borrowed from Latin or a Germanic translation, e.g. Swedish, Low German or High German, is uncertain.

köken: Suomi + -lainen. The reason for -a- as opposed to *suomelainen/*suomilainen is not entirely clear, although some kind of analogy with hämäläinen, karjalainen, vepsäläinen on the one hand and muukalainen, täkäläinen on the other may be possible.
Non-Sino-Vietnamese reading of Chinese 芬蘭 (SV: Phân Lan), perhaps euphemistically altered due to phân (“feces”) and the influence of phần (“part; portion”), from Mandarin 芬蘭 /芬兰 (Fēnlán).
