In real life we almost always use it about people, teams, companies, and countries, not about boats: a rudderless government, a company left rudderless after the boss left, a young person feeling rudderless. It is a little formal, the kind of word you meet in news and essays, and it is almost never a kind description — it says the group is lost.

In real life在現實生活裡 we almost always use it about people, teams, companies, and countries我們幾乎都是用它來講人、團隊、公司和國家，not about boats而不是船：a rudderless government群龍無首的政府，a company left rudderless after the boss left老闆離開後陷入群龍無首的公司，a young person feeling rudderless一個感覺群龍無首的年輕人。It is a little formal這個詞有點正式，the kind of word you meet in news and essays是你在新聞和文章裡會遇到的那種詞，and it is almost never a kind description而它幾乎從來不是一種善意的形容 — it says the group is lost它是在說這個團體迷失了方向。

You can say it of a feeling, too你也可以用它來形容一種感覺：after the exam she felt rudderless考完試後她覺得自己群龍無首。The literal sense字面上的意思，a boat with no rudder也就是一艘沒有舵的船，exists是存在的，but you will hardly ever need it但你幾乎用不到那個意思。Though actually不過其實，even then就算在那種情況下，writers usually want the picture, not the carpentry作者要的通常還是那個畫面，而不是船的木工細節。
