原因交代不出來
說明交不出來,是因為根本沒人找得到理由。
adjective · C1
Very surprising, and impossible to explain — you can see that something happened or that you feel a certain way, but no reason for it can be found.
無法解釋的、莫名其妙的
One way to hold this word: an account that never gets given. Somebody should be able to stand up and say why — and nobody does. Whether that is because no reason can be found, or because nobody is required to give one, is exactly what splits the word into its two uses.
The supplied etymology is simply un- + accountable, and accountable rests on account — to give the reason or the reckoning for something.
供應的字源就是 un- 加 accountable,而 accountable 又建在 account(交代、說明、算帳)上。所以這個字的字面意思是「交代不出來」。至於交代不出來的是原因還是責任,就由句子決定。
