How to use it
Two meanings: (a) if it doesn't work out, the only option left is A; (b) simply just A, nothing more.
- Meaning (a): 「Vるまでだ」 = if it doesn't work out, the only option left is A — 「だめならやり直すまでだ」 (if it fails, I'll just start over). A decisive, ready tone.
- Meaning (b): 「Vたまでだ」 = simply did A, nothing more (no other intention) — 「事実を言ったまでだ」 (I merely stated the facts). Used to explain oneself/defend one's actions.
- Distinguish the two meanings by the verb FORM: dictionary form → (a), past (た) form → (b).
Examples
失敗したら、また一からやり直すまでだ。
If it fails, I’ll simply start over from scratch.
責めたのではない、事実を述べたまでだ。
I wasn’t blaming anyone — I merely stated the facts.
Keep in mind
- Vる → a solution; Vた → a justification.
- A firm, decisive tone.
Common mistakes
-
Wrongだめなら、あきらめますまでだ。
If it doesn't work out, I'll just give up, that's all.
Correctだめなら、あきらめるまでだ。
「までだ」 attaches to the DICTIONARY form of the verb, not the 「ます」 form.
-
Wrong飲み放題は9時までだから、やり直すまでだ。
All-you-can-drink is only until 9 o'clock.
Correct飲み放題は9時までだ。
「9時までだ」 uses 「まで」 to indicate a time LIMIT, and is not this grammar pattern.
Exam tips
- 「Vるまでだ」 = the only option left; 「Vたまでだ」 = simply did it (used to explain oneself).
