人潮匯流的大空間
這一組把核心畫面用在地方上：幾條路通到同一片開闊的空間。

核心畫面
One way to hold this word: stand in the middle of a station hall and watch. Lines of people come in from the street, down from the platforms, up from the trains below, and for a moment they are all in the same wide open space before they scatter again. Several run into one point, and the point has room to hold everything that arrives. Whether the word is naming that space, the people filling it, or two streams meeting in a field, the same running-together is underneath it.

可以想成站在車站大廳的中間往四周看。人潮從街上進來，從月台上下來，從地下的列車走上來，有那麼一刻全都在同一片開闊的空間裡，然後又各自散開。幾條路匯到一個點上，而那個點大到裝得下所有到達的人。不管這個字是在講那片空間、講填滿它的人群，還是講野地裡兩條溪的交會，底下都是同一個「跑到一起」的畫面。From the word’s history
The word comes through Middle English and Middle French from Latin concursus, from concurrere, to run together — the same root as concur. The running-together is not a later metaphor; it is what the word says.
這個字經由中古英文和中古法文，來自拉丁文 concursus，源頭是 concurrere（一起跑），跟 concur 同一個字根。「跑到一起」不是後來加上去的比喻，而是這個字本來就在說的事。
