可以想成一扇沒有鎖上的門——它不一定會開，但那條路是通的。核心畫面比較像『這件事有辦法發生、有辦法去做』，一個還開著、事情可能在裡面發生的空間。From the word’s history
From Latin possibilis 'that can be done', from posse 'to be able'. At root the word is about ability — something being able to happen, or you being able to do it — and that 'able' is exactly what stretches into 'a chance', 'an option', and 'potential'.
來自拉丁文 possibilis（做得到的），源自 posse（能夠、有能力）。這個字的根本就是『能』——某件事能發生，或你能去做——正是這個「能」延伸成了「機會」「選項」和「潛力」。
