核心畫面

One way to picture 'extension': something is stretched out longer or made bigger — and often the new added length itself. Picture a road pushed further on, or the extra piece onto the end. From that one image of 'stretched longer / the added part', the word spreads in many directions: extra time, a wider reach, an added phone on the line, extra hair, an electric cable that reaches further, even the dot-letters added to the end of a file name.

可以想成： extension 的核心畫面是把某樣東西拉得更長、弄得更大——而且常常就指那段新加上去的部分本身。想像…更多收起可以想成： extension 的核心畫面是把某樣東西拉得更長、弄得更大——而且常常就指那段新加上去的部分本身。想像一條路往前再延伸出去，或末端接上的那一截。從這個「拉長／加上去的那一段」的畫面，這個字往很多方向散開：多出來的時間、更廣的觸及範圍、線上多接的一支電話、接上去的頭髮、伸得更遠的電線，甚至檔名末端加上的那幾個字母。
