じゃないか ⇒ やんかIsn't it?, Doesn't it?, Don't you?

When やん (an expression similar to でしょう) is paired with the sentence ending particle か, it slightly changes the nuance to something similar to じゃないか. This means that it can be translated as 'isn't it?'.

Although やんか is a combination of や (acting as an auxiliary verb), の (shortened to ん), and か (both acting as sentence ending particles), やんかis treated as a stand alone statement that may be attached to the end of almost any sentence, regardless of regular conjugation rules.

Occasionally, か may be replaced by かいさ. やんかいさ is similar to やんか, except that it more strongly conveys that the speaker is looking for an answer, or extra information. Additionally, やんかいさis more common in 京都(きょうと), as opposed to やんか, which is more common in 大阪(おおさか) (both cities within the 関西(かんさい) area.)
