I definitely don’t speak Finnish fluently but I do understand enough words to get by. I also have mastered the art of GoogleTranslate!
Alas most Finnish words don’t have the same roots as most Romance, Germanic or Slavic languages so it’s been quite an adventure not being able to rely on etymology to figure out what a word means. Most of the words I do know are basic greetings or related to food! As I live and work in the Helsinki region, it hasn’t been too problematic as most people do speak English (or at least understand enough to help me when I do need help).
