Distinguishing the conjunctions weil and denn in German

A1A2B1

After this lesson you can distinguish „weil“ and „denn“ and use them with correct word order in simple German sentences.

In this lesson you learn how to use the conjunctions weil and denn. Both introduce a reason, but they behave differently in the sentence: weil makes a subordinate clause, denn links two main clauses.

Basic meaning of „weil“ and „denn“

weil: gives a reason, focuses on the content of the explanation.
denn: also gives a reason, sounds a bit more neutral or written.

The key point is not meaning, but word order.

„weil“ – conjunction with a subordinate clause

weil introduces a Nebensatz (subordinate clause).
In this Nebensatz the finite verb goes to the end.
The weil-clause can stand after or before the main clause.

Word order with „weil“

Structure	Example	Meaning
main clause + , + weil-clause	Ich kann nicht kommen, weil ich krank bin.	I cannot come because I am ill.
weil-clause + , + main clause	Weil ich krank bin, kann ich nicht kommen.	Because I am ill, I cannot come.

More examples:

Er bleibt zu Hause, weil er keine Zeit hat. (He stays at home because he has no time.)
Weil er keine Zeit hat, bleibt er zu Hause. (Because he has no time, he stays at home.)

„weil“ and „da“

da can often replace weil, especially at the beginning of the sentence.
With da the verb is also at the end of the Nebensatz.

Example	Meaning
Weil es regnet, bleibe ich zu Hause.	Because it is raining, I stay at home.
Da es regnet, bleibe ich zu Hause.	Since / as it is raining, I stay at home.

„denn“ – conjunction between two main clauses

denn links two main clauses.
Word order does not change: verbs stay in position 2.
denn stands between the two main clauses and never at the very beginning of the sentence.

Word order with „denn“

Structure	Example	Meaning
main clause + , + denn + main clause	Ich bin müde, denn ich habe nicht geschlafen.	I am tired because I have not slept.
main clause + , + denn + main clause	Du solltest lernen, denn die Prüfung ist nächste Woche.	You should study because the exam is next week.

More examples:

Wir bleiben zu Hause, denn es regnet. (We stay at home because it is raining.)
Ich gehe früh ins Bett, denn ich muss morgen arbeiten. (I go to bed early because I have to work tomorrow.)

Comparison: „weil“ or „denn“?

Often both are possible, but the structure is different:

Variant	Example	Meaning
with „weil“	Wir bleiben zu Hause, weil es regnet.	We stay at home because it is raining.
with „denn“	Wir bleiben zu Hause, denn es regnet.	We stay at home, for it is raining.

Quick rules:

After weil: verb at the end of the clause.
After denn: verb in position 2 like in a normal main clause.
Do not start a sentence with denn followed by a second clause.

Small practice

Insert weil or denn and watch the word order:

Ich gehe jetzt ins Bett, ___ ich bin sehr müde.
___ ich sehr müde bin, gehe ich jetzt ins Bett.
Wir fahren nicht ans Meer, ___ wir haben kein Geld.
Er kommt nicht, ___ er krank ist.

Solutions (to check):

denn – Ich gehe jetzt ins Bett, denn ich bin sehr müde. (I am going to bed now because I am very tired.)
weil – Weil ich sehr müde bin, gehe ich jetzt ins Bett. (Because I am very tired, I am going to bed now.)
denn – Wir fahren nicht ans Meer, denn wir haben kein Geld. (We are not going to the sea because we have no money.)
weil – Er kommt nicht, weil er krank ist. (He is not coming because he is ill.)
