About this pattern

Explanation

かどうか is used to report or consider whether something is the case. It introduces an indirect question or a condition about truth, possibility, or decision. It’s often used when the speaker is unsure and wants to know or state the outcome of a situation. It can also turn a statement into a mental question about possibility or truth. The phrase can be used in both formal and casual contexts, typically in written or spoken language that involves thinking about a result or decision.
