I was learning about Finland earlier. I heard Finnish is a very difficult language. I wanted to see if it was worth taking the time to practice. I couldn't find it for English speakers. Will it ever be added to Duolingo?
It's the most requested language on Duolingo, and apparently Finnish is confirmed for Duolingo (I heard about that somewhere). The question is when. I along with several others are anticipating the opening of Finnish in the Incubator on December 6, Finland's 100th Independence Day. And yes, Finnish is quite difficult in terms of grammar but once you get the hang of it it becomes easy, since it's highly regular.
Pronouncing written Finnish is relatively straightforward, since every letter is pronounced and almost always in the same way, regardless of the surrounding letters. There are some new sounds, unless you already know related or Scandinavian languages.
There are a couple of unusual letters, which are also used in Swedish - å, ä, ö.
Difficult part: car - auto; go by car - menee autolla; on top of car - auton päällä; in car - autossa;
That is, rather than learning arbitrary prepositions, one must learn arbitrary endings one adds to words. The endings one uses depend on the context.
