The meaning of German “denn”

Hello everyone,

and welcome to our German Word of the Day.
And this time, we’re in for another one of those mysterious German particles that Germans are sprinkling all over the sentences, to give them “flavor”.
You know what I mean… those dochs and halts and jas and ebens.
And today, we’ll take a look at the meaning and use of


And we’ll start with a couple of quick fixed for common mistakes.
First of,there is a difference between German den and German denn and it matters! Denn is like the English word den, German den has a long, open “e”. Here they are.

den – denn


So please try to practice this.

And then second, a quick note about denn and dann because people often mix them up.
300 years ago, denn and dann were pretty much synonyms. But just as their English brothers then and than diversified in meaning, so did the German denn and dann.
So is the difference between denn and dann the same as between then and than?
Of course not.
That would go against rule number 42 of the Manifestum of Languages

42. The Confusion of the Learner must be achieved

Dann does NOT mean than and denn often DOESN’T translate to then.
I don’t want to talk about dann here so let’s just say dann  is essentially an answer to the question when?

  • Wann?
  • When?

Denn on the other hand cannot, under no circumstances ever, answer anything.
But it can do a lot of other things and we’ll clear them all up today.
So are you ready to jump in? Then let’s go…

Denn has three meanings; or better functions. There’s its normal day job as a translation for because to pay rent, then, like any employee in 2020 it seems, it has a side hustle as a flavoring particle, and that’s actually going great. And sometimes it has to help out its gym buddy als with the comparisons.
Let’s start with the day job, which is a translation for because.

“denn” and “weil” and the difference

Denn and weil are both translations for because, so they both introduce a reason. And yet, they’re not interchangeable – at least not without modifications. And the reason for that is the grammar and structure.
Weil is what in grammar jargon is called subordinating congestion… or … something like that. Let’s just call it intro-word – one of those words that are like “Verb, get out of my face!” sending the poor verb all the way to the end.

  • Ich esse eine Pizza, weil ich hungrig bin.
  • I eat a pizza, because I am hungry.

The second part of the sentence said as a statement alone would be:

  • Ich bin hungrig.
  • I am hungry.

Adding because in English doesn’t affect the structure at all; adding weil in German makes bin move to the end.
This does not happen with denn. Denn leaves the structure untouched.

  • Ich esse eine Pizza, denn ich bin hungrig.
  • I eat a pizza, because I am hungry.

You might be like “Awesome, I’ll just use denn then.” but that wouldn’t be very natural. This weird verb at the end stuff is at the very foundation of German (as I lay out in my articles on Word Order) so you shouldn’t just avoid weil.
Anyway, so yeah, weil makes the verb move, denn doesn’t.
So far so simple.
But there’s a second difference between denn and weil and we’ll have to wax a little nerdy for it… so please indulge me :).

A weil-sentence is basically a box with additional information about what is going on in the main statement, the main clause. It answers the question why? and it is like a child of the main sentence if you will. There are all kinds of such boxes (I talk more about this approach in a separate article, link below) . One tells us who, one tells us when, one tells us where and so on. It doesn’t matter what “form” the information has inside the boxes. So it can be just a word, or it can be a weil-sentence. What matters is that these boxes  additional information to the main action can be placed in different positions in the main sentence. It is not really crucial, where it is as long as it is given within the scope of the sentence.

  • Ich esse eine Pizza, weil ich Hunger habe.
  • Weil ich Hunger habe, esse ich eine Pizza.
  • Ich esse, weil ich Hunger habe, eine Pizza.

All three version mean the same and are fully 100% grammatical. They just sound a little different, have a different rhythm, a different style. And yes, I just said style in context of the German language. So… the weil-sentence can stand at various positions in a sentence.

This is NOT possible with denn. Yes, a denn-sentence does answer the question why, but it’s not integrated as a box into the main statement. It’s a second main sentence that related to the first one in way of reason. Denn creates the connection to what was there before, BUT for that to work, there has to be something. That’s why we can’t move the denn-part around.

  • Ich esse eine Pizza, denn ich habe Hunger. (right)
  • Denn ich habe Hunger, ich esse eine Pizza. (not right)

Grammatically, the second one is correct, but denn refers BACKWARD and there is nothing there. And the pizza-part is not connected to the denn-part at all and that makes its sound wrong.

Now you might be wondering if the only difference between denn and weil is how you have to set up your statement. And in most everyday contexts, we can say yes to that.
But because of their different functionality, there is one aspect where the two words do indeed have different skills.
And that is scope. We’ve learned that weil is an embedded sentence, a child. It is pretty much a part of a sentence just like a noun.
That’s why, unless the context is chrystal clear, the weil-part is perceived as belonging to what’s right next to it.
The denn-part on the other hand, being a main sentence on its own, can ONLY refer to other main sentences.
Sounds complicated but here’s an example

  • Die Chefin ist sauer, dass das Meeting gecancelt wurde,
                   – weil sie nach New York geflogen ist.
                   – denn sie ist nach New York geflogen.
  • The boss is pissed that the meeting was cancelled because she flew to New York
  • Because she flew NY just for this, the boss is pissed, that the meeting was cancelled.

The weil -part come after the meeting-part and thus the native speaker brain automatically assumes it is part of it. The New York-part gives the reason for the meeting being cancelled. It can technically also be part of the main sentence, but it’s not automatically perceived that way.
The denn-sentence on the other hand can ONLY refer to the main sentence and that is the sauer-part.  Denn can NOT be understood to refer to the meeting-part because the meeting-part is just a box in the main.

That said though… this difference in “scope” is not always a factor and it’s nothing to worry about for you when you speak. For the most part, it comes down to style and personal preference which one people use. Sometimes the denn-sentence just sounds better and the same expressed with weil would be boring. Google-ngram (which shows frequency in books) suggests that both of them are used equally often with a slight edge for weil. I’d say in daily speech, weil is used about 70 % of the time.
For you it will be enough to use weil and let denn slowly unconsciously sink into your active vocabulary.
And speaking of active… I want you all to get down to the floor and give me 20 push ups.
And if you’re now asking yourself “Why?” then we’re right at our next point. Denn, the particle. 

“denn” – a curious filler

Just like doch or halt or schon, denn is also used as a flavoring particle. Here is an example from daily speech.

  • “Hey, ich muss dir was erzählen.”
    “Was denn?”
    “Ich habe heute 100 Euro gefunden.”
    “Oh, wo denn?”
    “Auf der Strasse vor meinem Haus.”
    “Lädst du mich denn auf ein Bier ein?”
  • “Hey I have got to tell you something.”
    Oh What is it?”
    “I found 100 € today.”
    “Oh, and where?”
    “On the street, in front of my house.”
    So, are you going to invite me for a beer then?

If you look at how denn is used here, you might notice one thing: it is only used in questions. And that’s no coincidence, because:

Denn as a flavoring particle DOES ONLY WORK IN questions!

But what exactly does it do?
Well, in many instances it is basically padding. Yup, padding. A “naked” question word would sound rather harsh.

  • “Hey, ich habe heute was cooles gesehen.”
  • “Hey I’ve seen something cool today.”

To make this sound friendly you would need to lengthen it a lot while doing all kinds of turns with the melody… whaaaaaat? Both languages, English and German try to soften this by adding some filler like oh, and or was it or… denn.
just makes you sound less harsh and it gives you more options to express your feelings with tone and melody.
It DOESN’T, as many sources online suggest, signal interest. I mean, come on people… it’s a question! “Denn signals interest.” is a lazy ass explanation.
What it really is is padding, an extra syllable that gives you room to express yourself tonally. You can make it sound annoyed, surprised, super curious, angry… whatever you want.

  • “Hey, ich muss dir was zeigen.
    “Was denn.”
  • “Hey, I gotta show you something.”
    “Oh what ? /What is it?”

However, probably on account of its padding-power denn always sounds a bit casual. A detective would never ask the suspect where denn the money is because the padding-power of denn would take away the sharpness.
(Another argument against this “Signals interest”-nonsense, by the way. The detective is VERY interested in the answers, even without denn.)
Anyway, here’s a couple more examples…

  • Wo ist denn eigentlich meine Brille?
  • Oh by the way where are my glasses?
  • Wie hast du denn nur  IHRE Telefonnummer gekriegt?
  • How the hell did you get HER phone number?

As you can see, denn is not restricted to super short questions. Sure, these questions wouldn’t sound super harsh without denn.
I’d say in those examples denn gives the same flavor as an initial so does in English.
Sometimes it has a slight undertone of at least

  • “Mein Arm tut immer noch wahnsinning weh.”
    “Kannst du denn (wenigstens) schlafen?
  • “My arm still hurts incredibly.”
    “Can you sleep at least?”

But those are nuances that you’ll pick up over time.
The important takeaway is that denn is used to “pad” questions and possibly give you some room for your intonation to show your mood, so go ahead and start adding it to questions. Just don’t overdo it. Like… having a denn in EVERY question would be too much :).
Now, we’re almost done, but there’s one more thing I want to mention real quick.

One more thing I want to mention real quick

Geez headline, you had one job!! Do it again, and correct this time!

“Denn” – the other “als”

Contemporary German (hahaha… writing that was a real joy for some reason) uses the word als for unequal comparisons.

  • Thomas ist größer als Maria.
  • Thomas is taller than Maria.

But a few hundred years ago, German actually used denn for this purpose. No idea why people switched to als at some point, but be that as it may,  there are two occasions in which denn is still used that way. The first is to avoid double als. As you know als itself has a LOT to do and means a LOT of things so sometimes this happens.

  • Ich bin jetzt größer als als Kind.
  • I am now taller than as a kid.

Here we have a comparing als and a whatever you want to call that –als. In spoken German, I think most people don’t bother and say als als but in writing the comparing als will be replaced by denn. I have to say though, that this sounds really high class already. Do it and your German teacher will be secretly impressed.

  • Ich bin jetzt größer denn als Kind.

Alright… there is also one fixed expression that still uses denn to for comparison: denn je.

  • Herkules ist stärker denn je.
  • Herkules is stronger than ever.

This doesn’t even work with als. Denn je is still quite common but it certainly sounds like very high German. So if you drop a denn je in a sentence people will be secretly impressed by your level of German.
But other than that I would not recommend to use denn as than in German. Sometimes it works and you may read it here and there but at the least you will sound like your are stage acting and in the worst case people will be confused because denn has other meanings that are more common. But denn je is than ever so go ahead and make some jaws drop.

And that’s it for today. Yeay!!
This was our look at the meaning and use of denn. We’ve learned that can mean weil, but it has different grammar and a different scope and so at least in spoken German the more common denn is the question padding.
If you want to check how much you remember, you can take the little quiz I have prepared for you.
And of coure, if you have any questions or suggestions leave me a comment. I hope you enjoyed it.
Till next time.

Hey Emanuel,
Why the sentence
“Entschuldigung, wissen Sie denn, wie ich zum Markt komme?”
Is wrong?
I thought “denn” can be used in questions, long and short?

The W-questions with “denn” part is satisfying for me.

But for the Yes or No questions, in this case, “denn” would have the both function of paddling and referring backwards (as in first meaning with because).

This is what makes me confusing.

Hallo Emanuel, on Question 4 of the test, I thought the last choice “Thomas koch Pasta, Weil er Hunger hat” was one of your trick questions and not a typo–because it should be Thomas kochT, –but turned out it really was a typo!

Hi Emanuel,

Wie hast du denn nur die IHRE Telefonnummer gekriegt?

In this example sentence, why do you have “die” and “ihre” at the same time?

Many thanks:)

I just found this blog today and I’m really impressed. I really like this style of teaching and I thank you wholeheartedly for explaining this really well. There’s only one thing I can’t quite understand – the last question from the quiz. It lists some answers that use DENN in affirmative or imperative sentences as correct. Why is that so? Isn’t it always used in questions? Are they part of idioms?

I want to say a big thank you for your mentioning the Manifestum of Languages. I am having a great time! I never enjoyed the idea of being confused so much :)

Hi Emanuel. I am learning a lot with your blog!

You might find this article interesting on denn vs weil.

It mentions that both A-weil-B and A-denn-B can tell that B is the reason why A happens, but only A-denn-B can tell that B is the reason why you say or believe that A happens.


Die Straße ist naß, denn es hat geregnet.
Die Straße ist naß, weil es geregnet hat.
(the street is wet because it rained, regardless of my opinion)

Es hat geregnet, denn die Straße ist naß.
*Es hat geregnet, weil die Straße naß ist.
(I say/believe that it rained, because I perceive that the street is wet)

Apparently, this second kind of causal link, this reason for stating the fact instead of reason for the fact itself, can only be expressed with denn.

Hallo! Ich lerne seit vier Jahren Deutsch, weil ich es für meine Prüfungen lernen muss. Jedoch wurden meine Prüfungen abgesagen wegen dem Coronavirus und ich lerne doch Deutsch! Warum? Ich kann jetzt nicht aufhalten! Ich bin besessen! Also hab ich jeden Tag studiert und es hat viel verbessert, da deiner Blogs sehr fantastisch sind! Danke!

Great article!

I have a question about the test on this answer choice of the 2 questions of choosing the grammatically correct answer. This sentence ‘Weil er Hunger hat, kocht Thomas Pasta’, how is it correct in one question and wrong in another if the sentence is already grammatically correct?

It would be better if you got straight to the point.

Umm…I don’t want Emanuel to get to the point! This blog is more designed to review ideas we already have seen in class, or go more in depth on words we “know”. He shuffles around the edges. Many other blogs are TOO short, brief, basic and don’t give the full Sprachgefühl.

Thank you for your great blog. It is really helpful! And awesome! One point: Denn die Kinder sollen nicht nur Deutsch lernen, sie sollen auch ihre Muttersprache lernen. “Denn” in case is translated as “as”, but not as “because” can be used, as the first part of a sentence:) My college helped me to understand it:)

So in this example
Wie hast du denn nur die IHRE Telefonnummer gekriegt?

Nur here means ( the hell) ??? Or is it because that it came with denn?

It took me a while to understand the “Chefin ist sauer” sentence. It might help to compare with sentences linked with “und”:

Die Chefin ist sauer, dass das Meeting gecancelt wurde und sie nach New York geflogen ist.
Die Chefin ist sauer, dass das Meeting gecancelt wurde, und sie ist nach New York geflogen.

From the word order, it is easy to tell that:
The first sentence is saying: The meeting was cancelled and she flew to New York. The boss is angry about that.
The second sentence is saying: The meeting was cancelled. The boss is angry about that, and she flew to New York.

With “weil” and “denn” you have no choice about the word order. With “weil” the word order has to be like the first sentence and with “denn” it has to be like the second sentence.
Die Chefin ist sauer, dass das Meeting gecancelt wurde, weil sie nach New York geflogen ist.
Die Chefin ist sauer, dass das Meeting gecancelt wurde, denn sie ist nach New York geflogen.

Therefore it sounds as if they are saying
Weil sentence: The meeting was cancelled because she flew to New York. The boss is angry about that.
Denn sentence: The meeting was cancelled. The boss is angry about that because she flew to New York.

No, I’m learning German. I didn’t understand the difference between denn and weil until I read your article. Excellent site, but the way. Always interesting to read and I’ve learnt a lot from it.

Nice… I stumbled across this after being puzzled by Müller/Schubert:
Und ist’s mir denn entgangen
daß ich geweinet hab’?
and trying to figure out how “because” would fit in there…
btw, could you please enlighten on Schubert’s lyrics “Ob es” for “Und ist’s” I’m not at all familiar with German so I’m quite lost on that one

Very cool, I read “Was Denn” everywhere and I was wondering if Denn had any meaning. Now I understand it! I’m gonna add Denn to all my questions til I run out of it.
