From the word’s history

From Middle English reduccion, from Old French reducion, from Latin reductio; reduce + -tion.

源自拉丁文 reductio,就是 reduce 加 -tion。

Wiktionary

You can picture a line on a chart down, or a price tag crossed out and rewritten lower. Reduction is the name for that downward move itself — how much smaller something got, or the act of making it smaller.

可以想成圖表上的線往下掉一階,或是價錢牌上舊數字被劃掉、改寫成比較小的數字。reduction 就是在替這個「往下」的動作命名:東西變小了多少,或是把它弄小這件事。
