tanskankielen
Tanskankielen is a Finnish surname. Its etymology is thought to derive from a combination of Finnish words. "Tanski" is a given name, possibly a variant of "Tanja" or "Tanas," while "kielen" is the genitive case of "kieli," meaning "tongue" or "language." Therefore, "Tanskankielen" could literally translate to something like "Tanski's tongue" or "Tanski's language."
The surname is not particularly common in Finland, suggesting a more localized or historically specific origin.
