核心畫面
Picture a piece of open ground that looks exactly like any other. The grass is ordinary, the path is ordinary, and there is nothing to see. Under the surface, spread all over it, sit things that go off when they are on. Two features do all the work in this word: the danger is hidden, and it is everywhere in the area rather than in one marked spot.
可以想成一片看起來跟別處沒兩樣的空地。草是普通的草，小路是普通的小路，表面上什麼都看不出來。地面底下卻整片埋著一踩就…更多收起
可以想成一片看起來跟別處沒兩樣的空地。草是普通的草，小路是普通的小路，表面上什麼都看不出來。地面底下卻整片埋著一踩就會出事的東西。這個字真正在講的就兩件事：危險是藏起來的，而且是整片都有，不是標好的某一個點。From the word’s history
The packet's source gives the word as mine plus field, and lists the same compound in Dutch, German, Danish and Swedish. So the literal build - a field with mines in it - is the whole of the first meaning, and the second meaning borrows that picture whole.
這份資料的來源說，minefield 就是 mine（地雷）加 field（一片地），並列出荷蘭語、德語、丹麥語、瑞典語都有同樣的組合。所以字面上的組裝就是第一個意思的全部：一片埋著地雷的地。第二個意思則是把這個畫面整個借走。

比喻的雷區
把上面那片地整個搬到生活裡：表面看起來是件普通的事，實際上處處可能踩到雷。借的是畫面，不是歷史。
