The Difference Between Wissen and Kennen in German
You want to say “I know” in German, and suddenly you have two verbs staring back at you: wissen and kennen. That usually leads to hesitation, guessing, or sentences that sound slightly off. The good news: the difference is clear once you see the pattern. Use wissen for facts, information, and things you know intellectually. Use kennen for familiarity with people, places, and things you know from experience. Once you lock that in, German gets much easier.
At VerbPal, this is exactly the kind of distinction we want learners to produce, not just recognise. Reading the rule helps, but fluency comes when you can choose the right verb quickly in a real sentence.
Use wissen for facts, information, and answers
If you know a fact, a detail, an answer, or a piece of information, use wissen.
Think of wissen as “to know mentally.”
Examples:
- Ich weiß die Antwort. (I know the answer.)
- Weißt du, wo er wohnt? (Do you know where he lives?)
- Ich weiß nicht, warum sie zu spät ist. (I don’t know why she is late.)
- Wir wissen, dass der Zug um acht Uhr fährt. (We know that the train leaves at eight.)
- Sie weiß viel über deutsche Geschichte. (She knows a lot about German history.)
You also use wissen with clauses, especially when the thing you know is a full idea:
- Ich weiß, dass er heute arbeitet. (I know that he is working today.)
- Weißt du, ob das Restaurant geöffnet ist? (Do you know whether the restaurant is open?)
That makes sense if you remember that a clause expresses information, not familiarity.
You will also hear wissen when talking about knowing how to do something, often with wie:
- Ich weiß, wie man das macht. (I know how to do that.)
- Weißt du, wie das Spiel funktioniert? (Do you know how the game works?)
A useful shortcut: if you could replace “know” with “know the fact” or “know the answer,” you probably need wissen. In VerbPal practice, we push this by making you retrieve full sentence patterns like Ich weiß, dass… and Weißt du, wo…? so the structure becomes automatic.
Pro Tip: If what follows is an answer, a detail, a question word, or a whole clause, start by testing wissen first.
Use kennen for familiarity with people, places, and things
Use kennen when you know someone or something because you have met them, experienced them, visited them, heard them, or become familiar with them.
Think of kennen as “to be familiar with.”
Examples:
- Ich kenne Maria. (I know Maria.)
- Kennst du Berlin? (Do you know Berlin?)
- Wir kennen dieses Restaurant. (We know this restaurant.)
- Er kennt den Film nicht. (He doesn’t know the film.)
- Sie kennt meinen Bruder. (She knows my brother.)
You also use kennen with books, songs, films, brands, and ideas that you recognize from experience:
- Ich kenne dieses Lied. (I know this song.)
- Kennst du das Buch? (Do you know the book?)
- Wir kennen die Regel schon. (We already know the rule / are familiar with the rule.)
That last example can feel tricky. In English, “know the rule” sounds like information, so you may expect wissen. But German often uses kennen when you mean you are already familiar with the rule as a thing. If you mean you know what the rule says, wissen can appear in a different structure:
- Ich weiß, was die Regel ist. (I know what the rule is.)
- Ich kenne die Regel. (I’m familiar with the rule.)
That distinction matters.
A useful shortcut: if what follows is a noun referring to a person, place, song, film, city, restaurant, or object of familiarity, kennen is usually right.
Pro Tip: If you could naturally say “I’m familiar with…” in English, German usually wants kennen.
Use this cheat code: wissen = Wikipedia, kennen = connection. If it feels like a fact you could look up, choose wissen. If it feels like a person, place, or thing you have a connection to through experience, choose kennen. And remember Lexi’s favourite Germanic-language puzzle: German sentences are Lego. The verb goes in slot 2 in main clauses, and the verb cluster goes to the end in subordinate clauses. So: Ich weiß, wo Berlin liegt (I know where Berlin is), but Ich kenne Berlin (I know Berlin).
The core contrast: information vs familiarity
Here is the simplest way to remember the difference:
- wissen = knowledge about
- kennen = familiarity with
Let’s compare them directly.
Facts and information: wissen
- Ich weiß seinen Namen. (I know his name.)
- Weißt du die Uhrzeit? (Do you know the time?)
- Sie weiß nicht, ob er kommt. (She doesn’t know whether he is coming.)
Familiarity and experience: kennen
- Ich kenne ihn. (I know him.)
- Kennst du seine Schwester? (Do you know his sister?)
- Sie kennt Hamburg gut. (She knows Hamburg well.)
Now compare these pairs:
- Ich weiß, wo Paul wohnt. (I know where Paul lives.)
- Ich kenne Paul. (I know Paul.)
The first sentence gives information about Paul. The second says you are personally familiar with Paul.
Another pair:
- Weißt du, wie dieses Spiel funktioniert? (Do you know how this game works?)
- Kennst du dieses Spiel? (Do you know this game?)
The first asks about understanding. The second asks about familiarity.
This is why English speakers mix them up. English collapses both meanings into “know,” but German keeps them separate.
If you know French, this will feel familiar:
- French savoir ≈ German wissen
- French connaître ≈ German kennen
If you know Spanish, same idea:
- Spanish saber ≈ German wissen
- Spanish conocer ≈ German kennen
That parallel helps many learners because the split is not uniquely German. German just forces you to be more precise than English does. We see this constantly in VerbPal review sessions: once learners stop translating one English verb and start choosing between two German meanings, their accuracy improves fast.
Pro Tip: Ask yourself one question: “Do I know information, or do I know from familiarity?” That usually gives you the right verb in seconds.
Full conjugation of wissen in the present tense
wissen is irregular, and that matters because its present-tense forms do not behave like a regular verb. The most important forms to memorise are ich weiß, du weißt, and er/sie/es weiß.
Here is the full present-tense conjugation:
| Pronoun | Form | English |
|---|---|---|
| ich | weiß | I know |
| du | weißt | you know (informal) |
| er/sie/es | weiß | he/she/it knows |
| wir | wissen | we know |
| ihr | wisst | you know (plural informal) |
| sie/Sie | wissen | they / you know (formal) |
Examples:
- Ich weiß es nicht. (I don’t know.)
- Weißt du das? (Do you know that?)
- Er weiß die Adresse. (He knows the address.)
- Wir wissen schon Bescheid. (We already know about it.)
- Wisst ihr, wann der Film anfängt? (Do you know when the film starts?)
- Wissen Sie, wo der Bahnhof ist? (Do you know where the train station is?)
A very common beginner mistake is trying to build forms like ich wisse in normal present-tense statements. That is wrong here. Say ich weiß.
If you want extra drilling on irregular patterns like this, our German conjugation tables help you see the forms clearly, and inside VerbPal we make you produce them actively rather than just stare at charts.
Pro Tip: Memorise ich weiß as a chunk. If that form is automatic, the rest of wissen becomes much easier.
Full conjugation of kennen in the present tense
kennen is much more regular than wissen. It follows a standard pattern for a verb ending in -en.
| Pronoun | Form | English |
|---|---|---|
| ich | kenne | I know / am familiar with |
| du | kennst | you know (informal) |
| er/sie/es | kennt | he/she/it knows |
| wir | kennen | we know |
| ihr | kennt | you know (plural informal) |
| sie/Sie | kennen | they / you know (formal) |
Examples:
- Ich kenne den Lehrer. (I know the teacher.)
- Kennst du dieses Café? (Do you know this café?)
- Sie kennt meine Eltern. (She knows my parents.)
- Wir kennen die Stadt gut. (We know the city well.)
- Kennt ihr den Film? (Do you know the film?)
- Kennen Sie Herrn Weber? (Do you know Mr Weber?)
Because kennen is regular in the present tense, learners usually make fewer form mistakes with it. The harder part is choosing it when English pushes you toward a more general idea of “know.”
You can also look up specific forms in our VerbPal homepage tools or browse Conjugate kennen in German and Conjugate wissen in German when you want a quick reference.
Pro Tip: Don’t overthink the forms of kennen. Put your energy into choosing the right verb for the meaning.
Common mistakes English speakers make
Most wissen vs kennen mistakes come from direct translation. English says “know” for almost everything, so your brain reaches for one German verb and hopes for the best.
Here are the most common traps.
1. Using wissen for people
Wrong:
- Ich weiß Maria.
Correct:
- Ich kenne Maria. (I know Maria.)
People are not pieces of information. If you know a person, you are familiar with them.
2. Using kennen for facts
Wrong:
- Ich kenne nicht, wo er wohnt.
Correct:
- Ich weiß nicht, wo er wohnt. (I don’t know where he lives.)
A wo clause expresses information, so use wissen.
3. Using kennen when you mean “know how”
Wrong:
- Ich kenne, wie man das macht.
Correct:
- Ich weiß, wie man das macht. (I know how to do that.)
Again, this is knowledge, not familiarity.
4. Using wissen with cities when you mean familiarity
Wrong:
- Ich weiß Berlin.
Correct:
- Ich kenne Berlin. (I know Berlin.)
Cities, countries, restaurants, films, books, and songs usually take kennen when you mean experience or familiarity.
5. Mixing up “know him” and “know about him”
These are different in German:
- Ich kenne ihn. (I know him.)
- Ich weiß viel über ihn. (I know a lot about him.)
That distinction is powerful. German lets you say exactly what kind of knowledge you mean.
If verb position also trips you up in sentences like Ich weiß, dass…, read our guide to verb position in subordinate clauses and our breakdown of the German V2 rule. This is one of Lexi’s favourite reminders: German sentences are built like a puzzle. In main clauses, the finite verb sits in slot 2. In subordinate clauses, the verb cluster moves to the end. Get the verb choice right, then put it in the right place.
Pro Tip: When you make a mistake, don’t just correct the verb. Ask what kind of “knowing” you meant. That prevents the same error next time.
Reading the rule is step one. Using it fast in real conversation is step two. If you want to make wissen and kennen automatic, pair this guide with active drills in [Learn German with VerbPal](/learn/german), browse more explanations in the [VerbPal blog](/blog), and review exact forms in our [German conjugation tables](/conjugations/german/). Inside the app, we use spaced repetition with the SM-2 algorithm so the distinction comes back just as you are about to forget it.
Useful sentence patterns you can reuse
The fastest way to sound natural is to learn high-frequency sentence frames.
Useful patterns with wissen
- Ich weiß nicht. (I don’t know.)
- Weißt du das? (Do you know that?)
- Ich weiß, dass… (I know that…)
- Ich weiß nicht, ob… (I don’t know whether…)
- Weißt du, wo/wann/warum/wie…? (Do you know where/when/why/how…?)
Examples:
- Ich weiß nicht, ob er heute kommt. (I don’t know whether he is coming today.)
- Weißt du, wann der Kurs beginnt? (Do you know when the course starts?)
- Sie weiß, warum das wichtig ist. (She knows why that is important.)
Useful patterns with kennen
- Ich kenne ihn/sie. (I know him/her.)
- Kennst du…? (Do you know…?)
- Ich kenne das schon. (I already know that / am already familiar with that.)
- Wir kennen uns. (We know each other.)
- Ich kenne mich damit aus. (I know my way around that / I’m familiar with that.)
Examples:
- Kennst du diesen Ausdruck? (Do you know this expression?)
- Ich kenne das Restaurant nicht. (I don’t know the restaurant.)
- Wir kennen uns seit drei Jahren. (We have known each other for three years.)
That last one is especially useful: sich kennen means “to know each other.”
- Kennen Sie sich? (Do you know each other?)
- Wir kennen uns von der Arbeit. (We know each other from work.)
At VerbPal, we focus heavily on patterns like these because fluency comes from retrieving whole chunks, not just memorising isolated dictionary entries. Lexi may be a dog, but she is very opinionated about drilling complete sentence frames.
Pro Tip: Learn wissen and kennen inside fixed phrases, not as abstract vocabulary items. That is how they become automatic.
Mini quiz: can you choose the right verb?
1) Which is correct: Ich ___ nicht, wo er ist.
2) Which is correct: Ich ___ deinen Bruder.
3) Which is correct: ___ du, wie das funktioniert?
4) Which is correct: ___ ihr München?
Pro Tip: If you get these right while reading but wrong while speaking, you need more active recall, not more explanation.
A final way to remember wissen vs kennen
If you want one memory hook, use this:
- wissen = “I know a fact”
- kennen = “I know it from experience”
So:
- Ich weiß die Antwort. (I know the answer.)
- Ich kenne den Lehrer. (I know the teacher.)
- Ich weiß, dass er in Köln wohnt. (I know that he lives in Cologne.)
- Ich kenne Köln gut. (I know Cologne well.)
That is the whole system.
Once you stop translating directly from English, the choice becomes much more natural. And once you practise it enough, you stop pausing before every sentence. That is exactly why we built Learn German with VerbPal around repeated production: you see the distinction, retrieve it, forget it a bit, then meet it again at the right time through spaced repetition. Over time, ich weiß and ich kenne stop feeling like grammar and start feeling like instinct.
Pro Tip: Build two default chunks in your head: Ich weiß, dass… for information and Ich kenne… for familiarity. Then use them until the contrast feels boringly obvious.
FAQ
Is wissen always followed by a clause?
No. wissen can take a noun when that noun is information: Ich weiß die Antwort. (I know the answer.) But it very often appears with clauses: Ich weiß, dass… or Weißt du, wo…? (Do you know where…?)
Can I use kennen for people and places only?
Mostly, but not only. You also use kennen for things you are familiar with through experience, such as songs, books, films, restaurants, rules, and expressions.
Why is wissen irregular?
Historically, wissen developed differently from regular verbs. For learners, the practical point is simple: memorise the present forms, especially ich weiß, du weißt, and er/sie/es weiß.
Is this like French savoir/connaître or Spanish saber/conocer?
Yes. The split is very similar:
- German wissen ≈ French savoir ≈ Spanish saber
- German kennen ≈ French connaître ≈ Spanish conocer
What is the fastest way to stop mixing them up?
Use sentence patterns and active recall. Don’t just reread the rule. Produce examples like Ich weiß nicht, wo… (I don’t know where…) and Ich kenne… (I know / am familiar with…) until the distinction feels automatic. That is the kind of practice we built into VerbPal and the wider VerbPal blog.
