Why are Finnish words so long?

Like mentioned earlier Finnish can have some scary long words. Finnish people for sure aren’t afraid of long words. You can find even kids casually saying sytytystulppa or the number 1193 as tuhatsatayhdeksänkymmentäkolme. Intimidated already? Bear with me, it’ll get longer.

Think of an example. A simple word for house in Finnish is talo. Not too long yet, so let’s start to conjugate.

Talo – House

Talo-ssa – In the house

Talo-i-ssa – In the houses

Talo-i-ssa-ni – In my houses

Talo-i-ssa-ni-kin – Also in my houses

Talo-i-ssa-ni-kin-ko  – Also in my houses?


And trust me, we could go even further. Take a look at the funny picture below, it’s not far from truth!
