灌進一個人身上
最直接的一種：接受活力的是一個人的身體和腦袋。這也是最容易在生活裡遇到的用法。
verb · C1
If something invigorates you, it makes your body and your mind feel fresh, strong and full of energy again.
使精神振奮、使有活力
核心畫面
A useful way to hold this word is to look at its three parts: in, , and the ending that means to make. Picture energy being poured into something that had run low. Every use keeps that shape, and the only thing that changes is what is holding out the cup — a tired person, a flat team, or a quiet market. Because the picture starts with something running low, the word always carries a before and an after.
可以想成把這個字拆開來看：in（進入）＋ vigor（活力）＋ -ate（使…）。畫面就像把力氣倒進一個已經快空掉的…更多收起
可以想成把這個字拆開來看：in（進入）＋ vigor（活力）＋ -ate（使…）。畫面就像把力氣倒進一個已經快空掉的容器。每一種用法都是同一個動作。變的只是誰把杯子伸出來。可能是一個累壞的人。可能是一支沒勁的球隊。也可能是一個冷清的市場。因為畫面一開始就是「快空了」，所以這個字永遠帶著前後對比：之前沒勁，之後有勁。From the word’s history
The packet's source entry dates the word to 1646, borrowed from New Latin invigorare, and analyses it on the surface as in plus vigor plus -ate. That is exactly the picture above: to make vigour go in.
packet 裡的來源說明寫著：這個字最早出現在一六四六年，借自新拉丁文 invigōrāre；就字面拆解則是 in ＋ vigor ＋ -ate。這正好就是上面那個畫面——讓活力進去。所以理解它時，抓住「灌進去」這個動作就夠了。

灌進一群人或一件事裡
同一個倒水的動作，只是容器變大了：從一個人的身體，換成一群人的士氣，或一整個市場的熱度。前後對比也一起帶過去——本來冷，現在動。
