圍起來的東西
這一支離「擋在中間」的畫面最近，看得見也摸得到，所以放在最前面當底。
noun · B1
Fences, or the wood, metal, wire and other material that fences are made from.
圍籬（材料）
核心畫面
A useful way to hold this word: fencing is what a fence does, turned into a noun. A fence stands between two sides and keeps them apart. The wood and wire that do the keeping-apart are fencing. In the sport, the sword is what stands between you and the other player, and the whole skill is in keeping them off. In the crime word, a person stands between the thief and the buyer, and the goods pass through without the two ever meeting.

一種好用的想法是：fencing 就是「fence 這件事」變成名詞。fence 的畫面可以想成「擋在中間的東西」。擋在你家和外面之間的木板和鐵絲，那些材料就叫 fencing。用劍比賽時，擋在你和對手之間的是那把細長的劍，整套本領也叫 fencing。銷贓的人則是擋在小偷和買家中間，東西從他手上過去，兩邊不用見面。這只是幫助記憶的一條線，資料上並沒有這樣說。From the word’s history
Wiktionary records only this much: fencing comes from Middle English fensing, and is fence + -ing. That supports the -ing part — the doing of it, or the stuff used for it — but it does not say how the sword sense and the barrier sense separated, so the shared picture above is offered as a way to remember the word, not as its history.
手上的資料只記到這一步：fencing 來自中古英語 fensing，等於 fence 加 -ing。這說明了 -ing 的作用，也就是「做這件事」或「做這件事用的東西」。至於劍和圍籬這兩個意思怎麼分開的，資料沒有說，所以上面那條共通的線只是記憶用的想法，不是它的歷史。
