Subordinate clauses with ob

A2 · Elementary · Cases & Verbs

The rule

ob = whether, for indirect yes/no questions.

How it works

Ob (whether, if) introduces an indirect yes/no question. It is used when you report a question that could be answered with yes or no. The verb goes to the end of the clause. Compare Ich frage, ob er kommt (I ask whether he is coming) with the direct question Kommt er?

When to use it

Use ob (whether/if) to report a yes/no question, with the verb at the end.

Use cases

Examples

Common mistake

Using dass instead of ob for a question: "Ich weiß nicht, ob er kommt" is right.

Memory tip

Ob reports a yes/no question. Wh-questions use the question word: "Ich weiß nicht, wo er wohnt."
