Synchronicity is when two things happen at the same moment and feel connected, even though neither one caused the other. You think of an old friend, and that afternoon a letter from her arrives. Nothing made that happen — but it does not feel like nothing, and that feeling is what the word names.

Synchronicity is when two things happen at the same moment and feel connectedsynchronicity指的是兩件事同時發生、而且讓人覺得有關聯，even though neither one caused the other儘管兩者其實誰也沒造成誰。You think of an old friend你想到一個老朋友，and that afternoon a letter from her arrives結果那天下午她的信就到了。Nothing made that happen沒有什麼東西讓這件事發生——but it does not feel like nothing但感覺上又不像是巧合而已，and that feeling is what the word names這個字說的就是這種感覺。

The psychologist Carl Jung invented it for exactly this: meaningful coincidence. So the word carries a hint of the mysterious, and people reach for it when a coincidence seems too neat to be only a coincidence.

The psychologist Carl Jung invented it for exactly this心理學家榮格（Carl Jung）就是為了這個發明了這個字：meaningful coincidence有意義的巧合。So the word carries a hint of the mysterious所以這個字帶著一點神秘的味道，and people reach for it when a coincidence seems too neat to be only a coincidence當一件巧合巧到不像單純巧合時，大家就會用上這個字。

Careful speakers keep it separate from plain 'coincidence' (no meaning attached) and from 'synchronisation' (things deliberately made to match).

Careful speakers keep it separate from plain 'coincidence'講究的人會把它跟單純的「coincidence」分開 (no meaning attached)（沒有特別意義的巧合） and from 'synchronisation'也跟「synchronisation」分開 (things deliberately made to match)（刻意調成一致的東西）。

But be warned that people do use it loosely, especially in business and sport, to mean nothing more than good timing or a team working smoothly together — 'the synchronicity of the two dancers'. A strict teacher would call that a misuse; it is common enough now that you will meet it, so read the whole sentence before you decide which one someone means.

But be warned that people do use it loosely但要提醒你，大家也常常鬆散地用這個字，especially in business and sport尤其在商業和體育場合，to mean nothing more than good timing or a team working smoothly together只是想說時機抓得好，或團隊合作很流暢——'the synchronicity of the two dancers'像「the synchronicity of the two dancers」（兩位舞者的synchronicity）。A strict teacher would call that a misuse嚴格的老師會說這是用錯了；it is common enough now that you will meet it但現在這種用法已經常見到你一定會遇到，so read the whole sentence before you decide which one someone means所以要看完整句才能判斷對方指的是哪一種意思。
