被推開的那段距離
這一組最貼近原始畫面：你不在該在的線上，中間空出一段。差別只在這段空隙是剛剛發生（船被吹偏），還是已經累積成一筆帳（進度落後）。
noun · C1
The distance a boat or an aircraft is pushed sideways by the wind, away from the direction it is pointing.
（船或飛機）被風吹偏的橫向距離
核心畫面
Picture a boat with its nose pointed straight at the harbour, while a side wind quietly pushes it off that line. The sideways gap between where the boat points and where it actually goes is the leeway. Every other use keeps that gap: sometimes the gap is welcome room to move, and sometimes it is ground you have lost and have to win back.

可以想成一艘船。船頭直直對著港口，側風卻一直把船往旁邊推。船頭指的方向，和船實際走的路線，中間差了一段。那一段就是 leeway。其他用法都還留著這個「偏開來的空隙」。有時候這個空隙是好事，代表你不必完全照著線走，可以自己動一動。有時候是壞事，代表你已經被推離該在的位置，得想辦法補回來。From the word’s history
The packet's Wiktionary entry derives leeway from lee, the side of a ship away from the wind, plus way. So the word literally names the path taken toward the sheltered side, which is the sideways drift itself.
封包裡的 Wiktionary 記錄說 leeway 由 lee 加 way 組成。lee 指船上背風的那一側，way 是走的路。字面上就是「往背風那邊走掉的路」，也就是被風推開的那段偏移，正好是今天各種用法共同的起點。

規則裡留下的空間
同樣一段空隙，這次是被當成好事。你不必完全貼著那條線走，旁邊還有可以移動的餘地。
