I'm an absolute Japanese learning beginner. I came across this confusing sentence while I was reading a grammar guide book. Please help me : 飲むんだ。 I understand that の is substituted by ん as we speak, but I'm not sure what's the exact meaning of the whole sentence. "I drunk" or is it only an adjective and if so, what does it mean ?

    I drunk -> Sorry but I don't really understand, did you mean to type "I drank" or "I drink" ?

Unless the context proved otherwise, that would be a request/order. It would be masculine speech nearly 100% of the time.

"Drink it up!"

The "other" main usage of 「~~のだ/んだ」 is when you explain (rather assertively) the reason or cause for something.



"I drink (alcohol) because I couldn't sleep if I didn't drink!"

  • Thanks, so if we translate word by word, that would be : The thing (ん) is (だ)that let's drink (飲む), right ?

    Word-for-word translation is difficult here. I recommend that you memorize the two usages as if 「のだ/んだ」 were a set phrase or sentence-ender.

I just replied today to a question that I believe might concern the same topic you are being confused by (since you don't give much context is a bit hard to say for sure).

Anyway, if I'm correct it might be an interesting reading:

aru vs arun -- are they exactly the same grammar-wise?
