once and for all

Question

once and for all 點解?

Answer 1

Once and for all 一勞永逸、一了百了、徹底 (解決問題等)
舉例說, 醫生向患了心臟病的病人解釋, 藥物只能控制其病情, 惟獨手術才可令問題根治, 一勞永逸, 英文便是：Medication alone can only reduce symptoms of your illness. If you undergo surgery, you will be able to do away with your problem once and for all.
Another example：Leaders of the two countries will hold talks next week in an attempt to settle the border dispute once and for all ( 兩國的領導人下週將展開會談, 企圖徹底解決邊界糾紛 )
( 可見 once and for all 並非只是加強語氣那麼簡單, 它其實表示問題不僅獲得處理或解決, 而是永遠的解決, 不會再次出現 )

Answer 2

通常英語應說 once for all 而不需用 and 字.
字典的解釋是最後一次, 但在片語來解是一勞永逸或一次過解決的意思.
例句:
Let us settle the matter once for all.

Answer 3

相信「一了百了」是比較貼切的解釋

Answer 4

即係[一次過]

通常用黎加強語氣e.g. They break into the Forbidden City of China, and Wong must face the Chinese villains and stop the German General once and for all.此句即使唔用once and for all意思都好完整，但用了就有[一次過,一勞永逸]的意思.
