「elude」可以想成這樣一個畫面：一隻手伸出去合起來，掌心裡是空的。東西剛剛還在那裡。它沒有撞開誰，也沒有跑得比較快，只是手到的時候，它剛好不在那個位置。整個字的各種用法，都像從這個「撲了個空」的瞬間長出來的——不管撲空的是追捕的人、努力很久的你，還是正在回想的腦袋。From the word’s history
Latin ēlūdō is built from ē- ('out of', the short form of ex-) plus lūdō ('to play; to trick'). That is a getting-out done by playing rather than by force, which matches the way the modern word almost always means slipping aside, not breaking through.
拉丁文 ēlūdō 由 ē-（出來，ex- 的短形）加 lūdō（玩、耍花招）組成，字面上像「用花招玩出去」。這正好對上今天 elude 的感覺：靠的是巧勁與角度，不是硬碰硬。
