爭執中退的一步
核心畫面最直接的用法：兩邊在拉，其中一邊鬆手一點，事情才走得下去。讓出來的是立場，不是實體的東西。
compromise · noun · C2
Something you let the other side have, so an argument can stop and you can reach an agreement.
讓步
核心畫面
One way to picture it: something you were holding, pushed across the table to the other side. The point isn't the giving — it's that you didn't have to. There is always another party, and usually a tug-of-war behind it.
原本握在自己手上的一樣東西，鬆手推過去給對方。關鍵不在「給」，而在「本來不必給」——這東西原是我的、原是我可以守住的…更多收起
原本握在自己手上的一樣東西，鬆手推過去給對方。關鍵不在「給」，而在「本來不必給」——這東西原是我的、原是我可以守住的，是我選擇讓出來的。所以 concession 幾乎總是隱含一個對面：有另一方在要，有一場拉鋸在進行。讓出去的可能是談判裡的一步、一項權利、一個價格，甚至是一塊地。From the word’s history
Latin concessiō 'a grant, permission, conceding', from concēdō = con- + cēdō 'to go away, to yield'. The bodily move of stepping back and leaving space for the other side is the frame the whole word still runs on.
payload 記的拉丁文 concessiō 意思是「給予、允許、讓與」，動詞 concēdō 由 con- 加上 cēdō「走開、退讓」組成。這個「退一步」的身體動作比較像整個字的骨架：不是把東西丟出去，而是自己往後退，把原本佔著的位置空出來給對方。今天談判桌上的 make a concession、政府給出的特許權、票價上的優待，全都是同一個往後退的動作，只是退的東西不一樣。
payload 提供的詞源說明（Latin concessiō < concēdō = con- + cēdō，Wiktionary 條目）
Three branches
上面讓給你的權利
退一步的動作制度化了：讓的一方是政府、公司或主辦單位，握著資源和規則；讓出來的東西被寫成白紙黑字，變成一項可以行使的權利或優惠。核心畫面沒變，只是這隻手變得很大，而且是單向的。
special right, license · noun · C2
A special right a government or an employer lets a person or group have, or the act of giving that right.
特許／優惠
讓出來的那個攤位
抽象的權利落地成看得見的東西：先是那塊被讓出來的空間，再是空間裡賣的爆米花。核心畫面在這裡已經退到背景——說話的人多半不會想到「讓步」，但那個「別人的場地、讓我在這裡做生意」的結構還在。
concession stand, stall · noun · C2
A small shop or stall that sells food or goods inside a larger place that belongs to someone else, such as a mall or a sports ground.
專櫃／攤位
