To travel all the way around something and come back to where you started — classically, to sail around the Earth. Magellan’s crew is the story people reach for.

To travel all the way around something完整地繞著某個東西走一圈 and come back to where you started再回到出發的地方——classically, to sail around the Earth經典的用法就是航行繞地球一圈。Magellan's crew麥哲倫的船隊 is the story people reach for是大家最常想到的例子。

You can also circumnavigate an island, a lake, or a continent, by ship or, later, by plane. The core picture is a full loop, not a shortcut across.

You你 can also circumnavigate an island也可以 circumnavigate（環繞）一座島、a lake一座湖、or a continent或一塊大陸，by ship搭船、or, later, by plane或後來搭飛機。The core picture核心畫面 is a full loop是繞完整整一圈，not a shortcut across而不是抄近路穿過去。

People do stretch it: “circumnavigate the city” for driving the ring road, or even “circumnavigate a problem” for finding a way around it without facing it. That last stretch is real in journalism and talk, but it is looser than the travel sense, and in a careful classroom the word still wants a place you can go around.

People人們 do stretch it確實會延伸這個詞："circumnavigate the city"「circumnavigate the city」（繞城市一圈）for driving the ring road用來指開車繞環城道路，or even "circumnavigate a problem"或甚至用「circumnavigate a problem」（繞開一個問題）for finding a way around it without facing it來指不正面處理、繞道解決問題。That last stretch最後這個延伸用法 is real in journalism and talk在新聞和口語裡確實存在，but it is looser than the travel sense但比旅行的意思鬆散，and in a careful classroom而在講究的課堂上，the word still wants a place you can go around這個詞還是希望有個實際可以繞的地方。

You circumnavigate a thing; you do not just wander near it.

You你 circumnavigate a thing是繞著一個實際的東西走一圈；you do not just wander near it而不是只在附近閒晃。
