Picture something whole being opened along the lines where its parts already meet, and then laid out piece by piece so that each one can be seen on its own. The blade follows the joins; it does not hack. When the work is done, nothing is hidden inside any more — you can see what was attached to what. That is the picture the word carries, whether the thing being opened is a fish, an argument, or a stretch of .
From the word’s history
Wiktionary gives Latin dissectus, the past participle of dissecare 'to cut asunder, cut up', from dis- 'asunder' + secare 'to cut' — the same secare that sits inside section. The core image is almost the literal sense: cut into separate parts.
字源上，dissect 借自拉丁文 dissecare（切開），由 dis-（分開）加 secare（切）組成；同一個 secare 也留在 section 裡面。所以核心畫面幾乎就是字面意思——切成分開的幾塊。
