「[況]{いわん}や」 and 「[況]{ま}して」 usages


I just learned about 況や and 況して, I tried to search for some detailed grammar
point but nothing...

Are they the same? I saw both mean "not to mention..." but they seem different
from the way I saw them used.

Can they be used in everyday life?

> 誰にも倒されない・・・況してお前だ！ : I will not be defeated... certainly not by you!

Is it correct if I say that? If yes what does it change to add a 「や」 to 「況して」?

> 日本の経済はやばいよね。況や起こってる政治問題。: The economy of Japan is in a bad shape... Not to
> mention the current politic issues.

Is this one correct?

Thanks!




いわんや is archaic and is rarely used in the everyday language. However, まして or
ましてや is still used. Examples would be:

> 魚も食べられないのだから、まして肉など論外だ  
>  魚も食べられないのだから、ましてや肉など論外だ

They both have the same meaning, but ましてや gives a bit more emphasis and is
also a bit more archaic.

To your examples: `誰にも倒されない・・・況してお前だ！` does sound ungrammatical, you'd have to
say something like `誰にも倒されない・・・況してお前にはな！`.

Same for `日本の経済はやばいよね。況や起こってる政治問題`. You'd have to change it to
e.g.:`日本の経済はやばいよね。況や今の政治問題はもっとやばい。`
