An eventuality is a thing that might happen — and people usually say it when they are thinking about a bad or awkward possibility, and getting ready for it. We should plan for every eventuality means: think of the ways this could go wrong, and have an answer.

An eventuality一個eventuality is a thing that might happen就是可能發生的事 — and people usually say it人們通常會這麼說 when they are thinking about a bad or awkward possibility當他們在想不好或尷尬的可能性, and getting ready for it並為此做準備的時候。We should plan for every eventuality「我們應該為每個eventuality做準備」 means意思是: think of the ways this could go wrong想想這件事可能出什麼錯, and have an answer並準備好對策。

It is a formal, careful, office-and-news word. You would not tell a friend bring a jacket in case of that eventuality; you would say in case it rains, or just in case.

It is a formal, careful, office-and-news word這是個正式、謹慎，辦公室跟新聞會用的字。You would not tell a friend你不會跟朋友說 bring a jacket in case of that eventuality「帶件外套以防那個eventuality」; you would say你會說 in case it rains以防下雨, or just in case或就是「以防萬一」。

Though actually, it does not have to be a disaster — only something that is not certain yet. It sits next to possibility, but it sounds heavier, more like a plan for trouble. Do not mix it with eventually, which means in the end.

Though actually不過其實, it does not have to be a disaster它不一定要是災難 — only something that is not certain yet只是還不確定的事。It sits next to possibility它跟possibility很接近, but it sounds heavier不過聽起來更沉重, more like a plan for trouble比較像是在為麻煩做打算。Do not mix it with eventually不要把它跟eventually搞混, which means in the end後者的意思是「最後」。
