Form and connection

[Plain form] かどうか

Core Explanation

Learn かどうか for embedded yes/no questions expressing uncertainty.

Cultural Note

かどうか lets you gracefully suspend judgment mid-sentence — acknowledging you're uncertain with a grammatical structure rather than pretending to know.

Practical examples

I don't know whether it will rain tomorrow.
Do you know if this restaurant is good?
Please check whether he will come.

Common pitfalls

Build the base form before adding the pattern

Complete the required conjugation first. Do not keep polite and plain endings at the same time.

Match politeness to the situation

The examples are reliable starting points; relationships and context can still change the most natural wording.
