Finnish contains many unique words that perfectly capture the local culture and mindset.

You can’t translate these words directly into English with just a single word.

Learning these expressions gives you a deeper understanding of the Finnish way of life.

Below is a list of ten untranslatable Finnish words that every language learner should know.

1. Sisu

Sisu is perhaps the most famous Finnish word in the entire world.

It describes an extraordinary amount of stoic determination, grit, and resilience.

You have sisu when you push through a highly difficult situation against all odds.

It’s not just about momentary bravery, but rather sustained courage over a long period.

2. Kalsarikännit

This word literally translates to “underpants intoxication”.

Kalsarikännit is the act of drinking alcohol at home in your underwear with no intention of going out.

It beautifully highlights the Finnish appreciation for extreme comfort and relaxation during long, dark winters.

3. Löyly

Sauna culture is a massive part of everyday Finnish life.

Löyly specifically refers to the hot steam that rises when you throw water on heated sauna stones.

It also describes the overall feeling and physical heat inside the sauna.

You’ll hear this word constantly if you ever visit a public sauna in Finland.

4. Nonni

Nonni is arguably the most versatile word in the entire Finnish language.

Depending entirely on your tone of voice, it can mean almost anything.

It can mean “there you go”, “finally”, “stop it”, “oh well”, or “let’s get started”.

You’ll hear Finnish people use this filler word in nearly every conversation.

5. Tarkenee

Winters in Finland get incredibly cold.

The verb tarkenee means that the temperature is warm enough for you to be comfortable.

It usually implies that you aren’t freezing because you’re wearing enough layers of clothing.

6. Ruska

Ruska describes the exact time in autumn when leaves change into vibrant shades of red, yellow, and brown.

It’s equivalent to the concept of autumn foliage, but Finns treat it as a distinct season of its own.

Many people travel to Lapland specifically for a ruskaretki to witness the stunning autumn colors.

7. Jaksaa

The verb jaksaa means having the physical or mental energy to do something.

It goes far beyond just “can” or “being able to” do a task.

If you’re completely exhausted after a long day of work, you would say that you don’t jaksaa cook dinner.

8. Myötähäpeä

Myötähäpeä directly translates to “shared shame”.

It’s the intense feeling of second-hand embarrassment you get when someone else does something highly awkward.

This word perfectly captures the Finnish sensitivity to social embarrassment and public awkwardness.

9. Vahingonilo

This concept is the exact opposite of myötähäpeä.

Vahingonilo translates to “damage joy” and is the equivalent of the German word Schadenfreude.

It refers to the malicious joy or satisfaction you feel when witnessing someone else’s misfortune.

10. Sielunmaisema

Sielunmaisema literally translates to “soul landscape”.

It describes a specific place or type of scenery that you feel deeply connected to on a personal level.

For many Finnish people, their sielunmaisema is a quiet lake surrounded by a dense birch forest.
