帶進一個位子、一份榮譽
門裡面是一個「名分」：一個職位，或一份留著不拿掉的榮譽。兩種都靠一場典禮完成，也都幾乎只用被動。
verb · C1
To put someone officially into a job or a position of authority, usually in front of other people at a ceremony held for it.
使就任
核心畫面
Picture a door, and someone standing at it waiting to be led in. Induct is the leading-in: a person or a body with the right to do it takes you across the line, and after that you are inside. The Latin behind the word is in- meaning in, plus ducere meaning to lead. What lies inside the door changes from sense to sense — an office, a wall of honoured names, an army, the habits of a trade — but the picture holds every time. It is formal. Someone else does it to you, which is why the passive be inducted into is so common. And it is usually one marked moment rather than a slow change.

可以想成一扇門，還有一個站在門口等著被帶進去的人。induct 就是「帶進去」的那個動作：有權力的人把你領過那條線，從此你就在裡面了。拉丁文的 in-（往裡）加 ducere（引導）正好對上這個畫面。門裡面可能是一個職位、一面刻著名字的榮譽牆、一支軍隊，也可能是一行人心照不宣的做法。畫面都一樣：語氣正式、是別人把你帶進去（所以被動的 be inducted into 特別常見）、而且通常就是那一刻的事。From the word’s history
Wiktionary dates the word to 1350–1400, from Middle English induct, borrowed from Latin inductus, the perfect passive participle of indūcō — literally led in. The modern senses all keep that leading-in.
Wiktionary 把這個字追到 1350–1400 年的中古英語 induct，來自拉丁文 inductus，也就是 indūcō 的過去分詞，字面就是「被領進去的」。今天的每一個意思都還留著這個「領進去」。
