What is the meaning of のか and how does it differ from か? のか and のですか are two versions of the same thing - both are questions with の - but のですか is more formal due to the inclusion of です I wouldn't say のか has the same meaning as のですか, but it does have the same meaning if you disregard formality - のですか is the formal version of のか
What is the meaning usage of か? - Japanese Language Stack Exchange 0 I'm a bit confused about the usage of か I was taught that it means "or" or "whether", so why is this sentence (どの車にするか迷っています) translated as "I was undecided which car to choose "? What is the purpose of か in this sentence and why doesn’t it translate to "whether"?
