ても・
Choosing between “even if” and “even though”
Choose first by attitude, not by the English translation. Use ても・でも for a neutral result that remains true despite a condition, のに for an established fact whose result clashes with expectation, くせに when you openly blame someone, and たって・だって for the broad neutral pattern in casual conversation.
The quickest choice
Ask whether the first part is hypothetical or established, then decide how much feeling you want to show.
Neutral despite-condition
ても・でも
The result holds despite either a possible condition or an actual fact. This is the safest general choice.
English may use either “even if” or “even though”; context determines which reading fits.
Unexpected established fact
のに
Both situations are treated as real, and the second goes against a natural expectation. Disappointment, surprise, or regret is common.
It does not normally lead directly into a request, command, invitation, or statement of intention.
Blame or resentment
くせに
You want to criticize an inconsistency in a person's behavior, role, knowledge, or attitude.
This can sound insulting. Avoid it in detached reports and be especially careful when speaking about a superior.
Familiar conversational form
たって・だって
You want the broad meaning of the neutral form in casual speech, messages, or dialogue-like writing.
Use the full neutral form in ordinary exposition and formal writing.
The same fact, with or without a felt mismatch
It is raining now, but a match is continuing.
雨が降っていても、試合は続いています。
The match is continuing even though it is raining.
AnalyzeThis neutrally states that the rain has not changed the result.
雨が降っているのに、試合は続いています。
Even though it is raining, the match is still continuing.
AnalyzeThis presents the continuing match as contrary to expectation and can suggest surprise or concern.
Takeaway: ても can describe a fact without insisting that the speaker feels surprised. のに actively highlights the expectation that has been disappointed.
When the result is a request or intended action
ても・でも freely handles an open condition and can lead into what someone intends, requests, or decides to do. Because のに normally links established situations, it is not the usual choice before such a result.
道が混んでいても、六時までに来てください。
Even if the roads are busy, please come by six.
AnalyzeThe possible traffic should not prevent the requested action.
Disappointment is not the same as accusation
A younger brother has free time but does not help with the housework.
弟は暇なのに、家事を手伝ってくれない。
Even though my younger brother is free, he will not help with the housework.
AnalyzeThe speaker sounds disappointed, but the form itself does not force a hostile accusation.
弟は暇なくせに、家事を全然手伝わない。
My younger brother has plenty of free time, yet he does not help with the housework at all.
AnalyzeThe speaker now treats the brother's behavior as blameworthy.
Takeaway: If you only mean “this is surprising or disappointing,” choose のに. Choose くせに only when the sharper blame is intentional.
Full neutral form or casual conversational form
Rain tomorrow will not cause the festival to be canceled.
明日雨が降っても、祭りは行います。
Even if it rains tomorrow, the festival will be held.
AnalyzeThis neutral version works in both speech and general writing.
明日雨が降ったって、祭りはやるよ。
Even if it rains tomorrow, we are still having the festival.
AnalyzeThis version belongs in familiar conversation.
Takeaway: For verbs, the casual form follows the plain past-looking shape: 降った becomes 降ったって, while a voiced ending gives forms such as 読んだって.
