Think of a sack of rice with a small hole in one corner. Nobody is throwing the rice away. It simply leaks, a grain at a time, while people walk past. At the end of the week there is a little pile on the floor, and you can sweep it up and see exactly how much you lost. `Wastage` is that pile — the quiet losing, and the size of it. The ending `-age` is what adds the measuring: `waste` is the act, `wastage` is the amount that went.
From the word’s history
From waste + -age. The suffix -age often turns an action into the amount or result of that action, which is why this noun so easily sits next to a number or a percentage.
由 waste 加上字尾 -age 組成。-age 常常把一個動作變成「那個動作的量或結果」。這也解釋了為什麼這個名詞特別容易跟數字、百分比一起出現。
