Finnish is one of the two official languages of Finland. The other is Swedish.
The Finnish language doesn’t come from the same language family as Swedish, Danish, and Norwegian, which are all descended from Old Norse. Finnish is more closely related to Estonian and Hungarian, and other Uralic minority languages such as Livonian, Votic, Karelian, and Ingrian.
Unlike most European languages, Finnish has no grammatical gender. The term “hän” can stand for either “he” or “she”'.
The Finnish language also has no future tense, relying on context or the presence of words like huomenna (“tomorrow”) or kohta (“soon”).
There are very few Finnish loanwords in English. In fact, only one popular word comes to mind—sauna. Saunas originated in Finland, and are now a popular kind of health facility around the world.
The Finnish language’s propensity for compounding words has given rise to some of the longest possible in any language. Lentokonesuihkuturbiinimoottoriapumekaanikkoaliupseerioppilas clocks in at 61 letters, and serves as a cautionary tale for multilingual UI designers. It means “airplane jet turbine engine auxiliary mechanic non-commissioned officer student.
Of course, that’s probably not a word you’ll see in regular use. But Finnish also holds the Guinness World Record for the longest palindrome: saippuakivikauppias, which means “soapstone seller”.
