核心畫面
You can picture things falling into place around you: the shop is on your way home, the machine does the hard part, the meeting lands on a day you were free anyway. Convenience is that fit — how little the world makes you go out of your way.

可以想成事情剛好都湊在你這一邊：商店就在回家路上、機器幫你做掉最麻煩的部分、開會那天你本來就有空。convenience 講的就是這種「剛好合得上」——這件事讓你少繞多少路、少花多少力氣。From the word’s history
From Latin convenientia 'a meeting together, agreement, harmony', from convenire 'to come together; be suitable, be proper', built on com- 'together' + venire 'to come'. Things that 'come together' well are exactly what we now call convenient.
來自拉丁文 convenientia「湊到一起、相合」，動詞 convenire 是 com-「一起」＋ venire「來」，意思是「走到一起、正好合適」。所以這個字骨子裡講的是「合得上」：時間合得上、東西合得上你的需要。理解這一點，at your convenience（你方便的時候）和 marriage of convenience（為現實條件而結的婚）就都說得通了。
