Longest Finnish words

What is the longest word in Finnish?

Finding the longest word in Finnish is a tricky task, since technically there is almost endless amount of variations in Finnish language. Through conjugations we can create words that make sense. Or not. What do you think for example about the word Epäjärjestelmällistyttämättömyydelläänsäkäänköhän?

Check out the meaning of Epäjärjestelmällistyttämättömyydelläänsäkäänköhän here.

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?

So these are all real words, that we use in everyday language. Similar word in any given language, like in my house, talossani is pretty much everyday thing in finnish too. But when we come to the compound words things get a bit trickier.

Compound words in Finnish

Compound words are commonly used in Finnish. Sometimes it’s very hard to determine if the words should be written separately or together. Even natives make a lot of mistakes.

Maybe the best example from compound words is tietokone, meaning computer. But hang on, tieto means knowledge. And kone means machine. So when we say tietokone, we literally say knowledge machine. Weird? Maybe. Funny? For sure!

So in a nutshell, Finnish is a language where it’s easy to make compound words by smashing smaller words together until they stick to each other, forming one larger word.

This is heavy stuff. Let’s have mini break. Some talented individual made the picture below, it’s not far from truth!

What about the shortest words in Finnish?

The shortest word is simply EI or EN, meaning no, or I don’t. And in some dialects you can simply say E. 

So next time someone asks you is are ever going to study any other languages besides Finnish, just answer E.
