Start with the everyday core
These small words do the heavy lifting: the top of the frequency list that appears in almost every sentence. Learn them first; they cost little and buy a lot. (See the full method for learning German.)
Characterful & hard to translate
Now the fun part: the words with no clean English equivalent. These carry culture, not just meaning, and they stick precisely because they're vivid. Nouns are shown with their article, the way you should always learn them.
der Feierabend · noun
The free time after the working day ends, and the mood that comes with it. Not "evening" but "clocking-off time is sacred."
Ich habe jetzt Feierabend. I'm done with work for the day.
die Gemütlichkeit · noun
Warm, unhurried cosiness: soft light, good company, nowhere to be. The German cousin of Danish hygge.
Wir genießen die Gemütlichkeit. We're enjoying the cosy warmth.
das Fernweh · noun
Literally "far-sickness": an ache to be somewhere distant. The exact opposite of homesickness (Heimweh).
Ich habe Fernweh. I'm longing to travel far away.
doch · particle
A "yes" that contradicts a negative, plus a flavour word that softens or insists. English has no single equivalent.
„Du kommst nicht mit." „Doch!" "You're not coming." "Yes I am!"
die Schadenfreude · noun
Pleasure taken in someone else's misfortune. So useful that English borrowed it outright.
Ein bisschen Schadenfreude war dabei. There was a bit of schadenfreude in it.
sturmfrei · adjective
Having the place to yourself, with no one around to answer to, classically when the parents are away.
Heute habe ich sturmfrei. I've got the place to myself today.
der Kummerspeck · noun
Literally "grief bacon": the weight you put on from emotional eating. A whole feeling in one wry word.
Das ist alles Kummerspeck. That's all comfort-eating weight.
die Torschlusspanik · noun
"Gate-closing panic": the fear that time is running out to act, before a door shuts for good.
Mit vierzig kam die Torschlusspanik. At forty the fear of running out of time set in.
verschlimmbessern · verb
To make something worse precisely by trying to improve it. A blend of verschlimmern (worsen) and verbessern (improve).
Jetzt hast du es verschlimmbessert. Now you've "improved" it for the worse.
na ja · interjection
The verbal shrug: "well…", "meh", "sort of". Buys a second and lowers the stakes of whatever comes next.
Na ja, es geht so. Well, it's so-so.
How to actually learn them
Reading a list is pleasant; keeping the words is the trick. Two things make the difference. First, meet each word in a sentence, not as a bare gloss. That is why every entry above has one. Second, review on a schedule so they don't quietly fade, and learn each noun with its article so gender comes for free.
That's exactly the loop in Smisli: tap any of these words in a real German text and it becomes a flashcard, and spaced repetition brings it back right before you'd forget. Start with Feierabend and go from there.
