Free German lessons with guided practice, audio, and speaking support.

Welcome back — Lesson 39! In this short lesson we'll dig into asking for causes and giving clear reasons. Listen, repeat, and then try the short speaking tasks to make these phrases yours.

Level B1: You'll practice asking what led to something and explaining reasons in German with natural phrases like "Ist das der Grund, warum ...?", "Deshalb ...", and "Ich habe beschlossen, ..., wegen ...". This CEFR-aligned lesson focuses on saying why things happened, checking causes, and linking reasons to actions.

After this lesson you'll be able to:

  • Use common B1 phrases to ask about causes (e.g. "Wie kam es zu ...?", "Lag es an ...?").
  • Give and link reasons: say one reason, add another, and state the result ("Ein Grund ist, dass ...", "Deshalb ...").
  • Practice short spoken responses using the target phrases in everyday contexts.

1. Reading + Listening Practice

Hear core phrases, repeat aloud.

Ist das der Grund, warum ___?

Is that why ___?

Meaning: Is that why ___?

When to use: Use this to check if one situation explains another. After 'warum' follow a subordinate clause with the verb at the end.

Ist das der Grund, warum du abgesagt hast?
Is that the reason why you canceled?
Ist das der Grund, warum das Meeting verschoben wurde?
Is that why the meeting was postponed?

Ich habe beschlossen, ___, wegen ___.

I decided to ___ because of ___.

Meaning: I decided to ___ because of ___.

When to use: Use this to state a decision and its cause. After 'beschlossen' a zu-infinitive clause is common; after 'wegen' standard written German uses genitive, spoken German often uses dative.

Tip: Beginners sometimes use the wrong form after 'beschlossen' (e.g. *'beschlossen, gehe' instead of 'beschlossen, zu gehen').

Ich habe beschlossen, zu Hause zu bleiben, wegen des Regens.
I decided to stay at home because of the rain.
Ich habe beschlossen, früher zu gehen, wegen eines dringenden Anrufs.
I decided to leave earlier because of an urgent call.

Ich habe nicht ___, weil ich ___ war.

I didn't ___ because I was ___.

Meaning: I didn’t ___ because I was ___.

When to use: Use this to explain a negative action with a personal condition. The first blank often needs a Partizip II after 'habe nicht'; for movement or state-change verbs you may need 'bin nicht ___'. The second blank is often an adjective.

Tip: Confusing 'habe nicht' and 'bin nicht' with verbs of movement (use 'bin nicht gegangen', not 'habe nicht gegangen').

Ich habe nicht teilgenommen, weil ich krank war.
I didn't participate because I was sick.
Ich bin nicht gekommen, weil ich müde war.
I didn't come because I was tired.

Ein Grund ist, dass ___.

One reason is that ___.

Meaning: One reason is that ___.

When to use: Introduce a single reason among others. After 'dass' use a subordinate clause with the verb at the end.

Ein Grund ist, dass das Budget zu klein ist.
One reason is that the budget is too small.
Ein Grund ist, dass das Team zu beschäftigt war.
One reason is that the team was too busy.

Deshalb ___ ich.

That's why I ___.

Meaning: That’s why I ___.

When to use: Use 'Deshalb' to connect an explanation to a result. The conjugated verb comes immediately after 'deshalb': 'Deshalb gehe ich', 'Deshalb habe ich ...'.

Deshalb habe ich das Meeting abgesagt.
That's why I canceled the meeting.
Deshalb lerne ich jetzt mehr.
That's why I am studying more now.

Ich frage, weil ___.

The reason I ask is ___.

Meaning: The reason I ask is ___.

When to use: Use this short, natural phrase to explain why you are asking. After 'weil' use a subordinate clause with the verb at the end.

Ich frage, weil ich die Frist nicht kenne.
I'm asking because I don't know the deadline.
Ich frage, weil mir die Informationen fehlen.
I'm asking because I'm missing the information.

Wie kam es zu ___?

What led to ___?

Meaning: What led to ___?

When to use: Ask this when you want to know how a situation or event happened. After 'zu' use the dative (e.g. 'zu der Verzögerung', often contracted 'zur').

Wie kam es zu der Verzögerung?
What led to the delay?
Wie kam es zu diesem Fehler?
What led to this mistake?

Lag es an ___?

Was it due to ___?

Meaning: Was it due to ___?

When to use: Use this to test whether a specific factor caused something. After 'an' use the dative: 'Lag es am Wetter?', 'Lag es an dir?'.

Tip: Beginners sometimes use accusative after 'an' here; remember this construction takes dative (e.g. 'am Wetter').

Lag es am Wetter?
Was it due to the weather?
Lag es an der Software?
Was it because of the software?

Ich dachte, ___, also habe ich ___.

I thought ___, so I ___.

Meaning: I thought ___, so I ___.

When to use: Use this to explain an action based on your belief. After 'dachte' you can include a full clause; after 'habe ich' usually Partizip II, or 'bin ich ___' for some verbs.

Ich dachte, das Meeting sei abgesagt, also habe ich nicht teilgenommen.
I thought the meeting was canceled, so I didn't participate.
Ich dachte, der Bericht sei vollständig, also habe ich ihn abgeschickt.
I thought the report was complete, so I sent it.

Das Problem war, dass ___.

The problem was that ___.

Meaning: The problem was that ___.

When to use: Use this to state the cause of a problem or the main issue. After 'dass' follow a subordinate clause with the verb at the end.

Das Problem war, dass die Daten fehlten.
The problem was that the data were missing.
Das Problem war, dass niemand informiert war.
The problem was that no one was informed.

Es gibt ein paar Gründe.

There are a few reasons.

Meaning: There are a few reasons.

When to use: Use this to signal that you will list multiple reasons: 'Es gibt ein paar Gründe.' then continue with examples or 'Ein Grund ist ...'.

There are a few reasons why we postponed.
Es gibt ein paar Gründe für meine Entscheidung.
There are a few reasons for my decision.

Ein weiterer Grund ist, dass ___.

Another reason is that the team is overloaded.
Ein weiterer Grund ist, dass die Kosten gestiegen sind.
Another reason is that costs have risen.
