Over the years I’ve learned to accept as normal the many differences and quirks Finnish has for someone learning it as a second language. Some of the most hilarious I’ve seen or heard from others below:

Olen iloinen = I’m happy
Olen loinen = I’m a parasite

Minä välitän sinusta = I care about you
Minä valitan sinusta = I (will) complain about you

Minun kieli on turvonnut = My tongue is swollen
Minun kulli on turvonnut = My dick is swollen (happened to a guy who had just gotten a tongue piercing)

kolari = car crash
Kolari= town in Finnish Lapland where snow (or something like it) fell this week
