核心畫面

Think of one clean stroke of a blade. The cut goes all the way through, the edge is smooth, and the two sides come apart with nothing ragged left in between. English uses that picture for ideas: a clear-cut rule or difference separates , so nobody has to argue about the middle. It also uses it for land, where the cutting was so complete that a bare patch stands out inside the forest.

可以想成一刀乾淨地切下去。切口平整,兩邊分得開,中間沒有拖泥帶水的毛邊。英文把這個畫面用在判斷上:a clear-c更多收起可以想成一刀乾淨地切下去。切口平整,兩邊分得開,中間沒有拖泥帶水的毛邊。英文把這個畫面用在判斷上:a clear-cut rule、a clear-cut distinction,都是「界線清楚到不用爭」。所以它的否定 not clear-cut 特別常見,意思是中間有一塊模糊地帶。同樣的畫面也被用在土地上:一整片林子砍到一棵不留,森林中間就切出一塊光禿禿的區塊。

From the picture

被砍到一棵不留的林地

同一個「切得乾淨、什麼都不含糊」的畫面,這次落在真的樹上:不是挑著砍,而是整區砍光,於是森林裡切出一塊邊界分明的空地。這是理解上的連結,不是在說哪一個用法先出現。這個名詞主要在美式英文裡使用。
