喜樂美語

Picture a single tick of a counter: it happens one time. That bare idea — 'one occurrence' — is the seed of every use of 'once'. Counting from it, you can place that single time in the present (right now, at once), in the past (it happened once / it was once true but not now), or set it as a rule about how often (once a week). And because 'one time something happens' naturally marks a turning point, 'once' also becomes the hinge that joins two clauses: once X happens, Y follows. The many (once and for all, once in a blue moon, once bitten...) are all this same 'one time' frozen into set phrases.

可以想成計數器「答」的一下：發生了一次。這個最素的概念——「一次、一回」——是 once 所有用法的種子。從這顆種子數下去，你可以把這「一次」放在現在（此刻、立刻 at once）、放在過去（曾經發生過一次／曾經如此但現在不是了），也可以把它定成頻率規則（一週一次 once a week）。又因為「某事發生那一次」天生就是個轉折點，once 還變成串起兩個句子的關節：一旦 X 發生，Y 就跟著來。那一堆片語（once and for all、once in a blue moon、一朝被蛇咬…）也都是同一個「一次」被凝固進固定說法裡。
