About じゃないか

When learning じゃない and ではない, we briefly mentioned that these constructions are regularly partnered with the particle , in order to form a (usually casual) question. In this lesson, we will further explore this usage.

Unlike じゃない and ではない (which need to come after a noun or な-Adjective), じゃないか is able to be attached to the end of almost any phrase, to indicate a question. This is very similar to finishing a sentence with 'isn't it?' in English.

When じゃないか is too casual, ではないか will be used instead. Despite being more formal, this may sound a bit stiff at times, so is best only used when politeness is expected.

Examples

--:--

    そのことじゃなかったか

    It was about that, wasn't it?

    もう()るんじゃないか

    It will finish already, won't it?

    あれカメラじゃないか

    Isn't that a camera!?

    (つぎ)(えき)()んじゃないか

    The next station is the one we get off at, isn't it?

    この(はし)(わた)(こわ)んじゃないか

    It is scary crossing this bridge, isn't it?

    It’s super confusing that de wa nai ka is the polite example, but it’s not accepted as a correct answer. They only except desu.

    I’m noticing all the examples with いadj or verbs before じゃないか add 「ん」, but なadj and nouns don’t. Is this a rule? I don’t see it mentioned in the structure section.
