1. Reading + Listening Practice

Hear core phrases, repeat aloud.

Ich komme nicht mit.

I can't follow.

Meaning: I can't follow.

When to use: Say this when someone speaks too quickly or the explanation is confusing and you can't keep up.

Tip: Don't drop 'mit' — saying only 'Ich komme nicht' changes the meaning.

Entschuldigung, ich komme nicht mit. Kannst du das langsamer erklären?
I can't follow. Can you explain that more slowly?
In der Diskussion komme ich nicht mit; es geht sehr schnell.
I can't follow the discussion; it's going very fast.

Ich bin mir nicht sicher.

I'm not sure.

Meaning: I'm not sure.

When to use: Use this reflexive phrase when you are uncertain about a fact or decision.

Tip: Beginners sometimes omit 'mir' — the correct form is 'Ich bin mir nicht sicher.'

Ich bin mir nicht sicher, ob der Bus pünktlich ist.
I'm not sure if the bus is on time.
Bei dieser Antwort bin ich mir nicht sicher.
I'm not sure about this answer.

Ich habe keine Ahnung.

I have no idea.

Meaning: I have no idea.

When to use: A casual, stronger way to say you don't know — common in spoken German.

Tip: Don't overuse in very formal situations — it's more casual than 'Ich weiß es nicht.'

Wie funktioniert das? Ich habe keine Ahnung.
How does this work? I have no idea.
Wer hat die Aufgabe? Ich habe keine Ahnung.
Who has the task? I have no idea.

That's expensive. — Yes, that's right.

Das stimmt nicht.

That's not true / That's not right.

That's not true; the information is wrong.
Er sagt, er war da, aber das stimmt nicht.
He says he was there, but that's not true.
