核心畫面
You can picture inform as putting something into someone's head that was not there before, so that afterwards their picture of the situation is different. Usually what goes in is facts and the person now knows; sometimes what goes in is deeper — an experience or an idea that quietly shapes everything the person makes.

可以想成 inform 是「把東西放進某人腦袋裡，放進去之後那個人對事情的畫面就不一樣了」。多數時候放進去的是消息，對方因此「知道了」；但這個字還有比較深的一面——放進去的是一段經歷或一種想法，它不會被講出來，而是慢慢把這個人做出來的東西塑成某個樣子。From the word’s history
From Latin informare, literally 'to shape, give form to', from in- ('into') + formare ('to form, shape'), from forma ('form'). It came into English in the early 14c. through Old French informer, first meaning 'to train or instruct in some subject'; the sense 'report facts or news, communicate information to' developed by the late 14c.
inform 來自拉丁文 informare，字面是「給它一個形狀、把它塑成型」（in- 進去 + formare 成形，來自 forma 形狀）。14 世紀初經古法文進入英文時，指的是「教導、訓練某人」，也就是把一個人的腦袋塑出形狀；到 14 世紀末才長出「把消息告訴某人」的意思。知道這一層，第二個用法就不奇怪了——說某人的作品 is informed by 某段經歷，講的正是這個字最原始的意思：那段經歷給了作品形狀。

在背後把它塑成這個樣子
放進去的不是一則消息，而是一整套經驗或想法，而且它不是被說出來，是滲進成品裡變成它的形狀——這正是 informare「給形狀」的原意。
