German: Giving Reasons with weil and denn
Learn to give simple reasons for your opinions in German using weil and denn, with correct word order and clear elementary examples.

In German, giving a reason for your opinion is a core conversation skill. You can say Ich mag Berlin, weil die Stadt interessant ist ('I like Berlin because the city is interesting') or Ich mag Berlin, denn die Stadt ist interessant. Both mean 'because', but they change word order. This lesson teaches the two most common ways to give a reason at elementary level: weil and denn. You will learn where to put the verb, how to answer Warum? ('Why?'), and how to keep your reasons short and clear.
By the end, you can…
- give a simple reason for an opinion using weil with the verb at the end.
- give a simple reason using denn with normal word order.
- answer the question Warum? in a short, correct sentence.
Listen once. Try it slowly. Then say it without looking.

Ich mag Berlin, weil die Stadt interessant ist.
I like Berlin because the city is interesting.
ikh mahk ber-LEEN, vyle dee shtat in-teh-reh-SANT ist
weil sends the verb ist to the end of the clause.
Ich mag Berlin, denn die Stadt ist interessant.
I like Berlin because the city is interesting.
ikh mahk ber-LEEN, den dee shtat ist in-teh-reh-SANT
denn keeps normal word order: subject + verb.
Warum magst du Berlin?
Why do you like Berlin?
vah-ROOM mahkst doo ber-LEEN
Warum? asks for a reason and often gets a weil or denn answer.
Ich lerne Deutsch, weil ich in Deutschland arbeiten möchte.
I am learning German because I would like to work in Germany.
ikh LER-ne doych, vyle ikh in DOYCH-lant AR-bai-ten MERKH-teh
möchte is a polite way to say 'would like'; the verb goes to the end after weil.
Ich nehme den Bus, denn er ist billiger.
I am taking the bus because it is cheaper.
ikh NAY-me den boos, den air ist BIL-ee-ger
denn links two main clauses without changing word order.

Make it make sense
Useful pattern
Use weil when you want to give a reason in a subordinate clause. After weil, the conjugated verb moves to the end: Ich bleibe zu Hause, weil ich müde bin ('I am staying home because I am tired'). Use denn when you want to keep normal word order: Ich bleibe zu Hause, denn ich bin müde. Both are correct. Weil is the standard choice in both spoken and written German; denn is also common but sounds slightly more formal or explanatory. Remember: weil + verb at the end; denn + subject + verb.
When to use it
Use weil or denn to answer Warum? and to support opinions such as Ich finde Deutsch schwer ('I find German difficult') or Ich mag Tee ('I like tea'). For example: Ich finde Deutsch schwer, weil die Grammatik anders ist. Ich mag Tee, denn er ist gesund. In everyday speech, weil is very frequent. Denn sounds a little more formal or explanatory, but it is still common. Do not use dass ('that') for reasons: Ich denke, dass Deutsch schwer ist means 'I think that German is difficult', not 'because'.
Listen to each line, then take one part and reply out loud.
Warum lernst du Deutsch?
Why are you learning German?vah-ROOM lernst doo doychIch lerne Deutsch, weil ich in Berlin studieren möchte.
I am learning German because I would like to study in Berlin.ikh LER-ne doych, vyle ikh in ber-LEEN shtoo-DEE-ren MERKH-tehInteressant. Und warum Berlin?
Interesting. And why Berlin?in-teh-reh-SANT. oont vah-ROOM ber-LEENIch mag Berlin, denn die Stadt ist lebendig.
I like Berlin because the city is lively.ikh mahk ber-LEEN, den dee shtat ist leh-BEN-dikhA little context goes a long way
In German-speaking countries, weil is the standard everyday way to give a reason. Denn is also correct and often sounds slightly more formal or deliberate. In Switzerland and Austria, weil is common too, but in informal Swiss German speech you may hear the verb not at the end; in standard written German, keep the verb at the end after weil. Use Sie with strangers and du with friends when asking Warum?
One thing to watch for
Ich mag Berlin, weil die Stadt ist interessant.
Try this instead: After weil, the verb must go to the end: Ich mag Berlin, weil die Stadt interessant ist. If you want normal word order, use denn: Ich mag Berlin, denn die Stadt ist interessant.
Your turn
Try answering out loud before checking a possible answer.
1Complete: Ich trinke Kaffee, weil ich munter ___ (sein).
Show a sample answer
Ich trinke Kaffee, weil ich munter bin.
The verb sein is conjugated as bin and goes to the end after weil. You could also say Ich trinke Kaffee, denn ich bin munter.
2Rewrite with denn: Ich gehe ins Kino, weil der Film gut ist.
Show a sample answer
Ich gehe ins Kino, denn der Film ist gut.
Denn keeps normal word order: subject der Film + verb ist. The meaning stays the same.
3Answer in German: Warum lernst du Deutsch?
Show a sample answer
Ich lerne Deutsch, weil ich in Deutschland arbeiten möchte.
This answers Warum? with weil and puts möchte at the end. Other reasons are fine, for example weil ich die Kultur mag.
Use weil with the verb at the end and denn with normal word order to give simple reasons for your opinions in German.
