About のではないだろうか

のではないだろうか is a fairly long grammar pattern in Japanese that is used when one wants to express their opinion indirectly, in the form of a rhetorical question. Common translations include 'I think it's (A), isn't it?', and 'it might be that (A)'. However, being that this is just a combination of の, ではない 'isn't', だろう 'probably', and か, the literal meaning is simply 'is it probably not that it's (A)'. Just like in English, the elongation of the phrase and not saying anything with certainty makes it sound more modest.

のではないだろうか may be seen following verbs and い-Adjectives, or な-Adjectives and nouns when preceded with な. Additionally, でしょう may replace だろう.

This phrase can also be used when seeking agreement from the listener, or when mildly trying to persuade them that your way of thinking may be correct.

    The structure details for this grammar point

    Noun + (なの(3))+ ではない(2)(だろう)か
    
    (2) じゃない
    (3) なん
    

    indicate nouns can be inflected with なの・なん, but this doesn’t appear to be reflected in the examples, nor accepted in any of the answers I’ve encountered so far. I already reported this previously, but thought I should post here as well to bring attention to this discrepancy.

    This still appears to be the case or am I doing something wrong?
