把年輕放回去
兩個意思是同一個動作，差別只在對象：一個是人的身體和精神，一個是地方或組織的生命力。
verb · C1
To make someone look or feel young, fresh, and strong again, the way a long rest, a holiday, or a treatment can.
使恢復青春活力
核心畫面
Think of the word as running a clock backwards on something that has got old and tired. A face, a street, a company — the same thing is still there, but the years are taken off it and the energy comes back. Nothing is replaced; what was already there is made young again. That is why the word always needs a worn-out 'before' behind it.
可以想成把時鐘往回轉。對象已經舊了、累了，而這個動作把它身上的年歲拿掉，把力氣放回去。一張臉、一條老街、一家公司都行…更多收起
可以想成把時鐘往回轉。對象已經舊了、累了，而這個動作把它身上的年歲拿掉，把力氣放回去。一張臉、一條老街、一家公司都行。重點是東西沒有換掉，是原來那個被弄年輕了。所以這個字後面永遠站著一個「以前很累」的前提，少了那個前提，句子就會怪。From the word’s history
The source gives re- (again) plus Latin iuvenis (young) plus -ate, so the word literally means to make young again.
來源把這個字拆成 re-（再一次）＋拉丁文 iuvenis（年輕）＋ -ate（動詞字尾），字面就是「使再年輕」。這條線索直接就是今天的核心畫面，兩個意思都只是把它用在不同對象上。
