A group of three people who together hold the power in something. The core sense is Roman history: in ancient Rome a triumvirate was a formal alliance of three men ruling the state — most famously Caesar, Pompey and Crassus.

A group of three people一群三個人 who together hold the power in something他們一起掌握某件事的權力。The core sense核心的意思 is是 Roman history來自羅馬史：in ancient Rome在古羅馬，a triumvirate was a formal alliance of three men ruling the state triumvirate是指三個人正式結盟、共同統治國家——most famously最有名的例子 Caesar, Pompey and Crassus就是凱撒、龐培和克拉蘇。

Modern English keeps that shape but uses it loosely for any powerful trio: the three executives who really run a company, the three ministers who decide policy, the three writers who shaped a whole style of music.

Modern English現代英文 keeps that shape保留了這個形式，but但 uses it loosely for any powerful trio鬆散地拿來指任何有權力的三人組：the three executives who really run a company像真正在管理一間公司的三位主管、the three ministers who decide policy決定政策的三位部長、the three writers who shaped a whole style of music塑造出整個音樂風格的三位作曲家。

Two things give the word its flavour. First, the three are roughly equal — it is not a leader with two helpers, it is power genuinely shared, which is also why real triumvirates tend to break apart when one member wants more. Second, it sounds formal and a little grand, so journalists and writers often use it half-jokingly for smaller trios ("the triumvirate that runs the school canteen").

Two things兩件事 give the word its flavour賦予這個字它的味道。First第一，the three are roughly equal三個人的地位大致相等——it is not a leader with two helpers不是一個領袖帶兩個助手，it is power genuinely shared而是權力真正地分享，which is also why real triumvirates tend to break apart when one member wants more這也是為什麼真正的triumvirate常常會在有人想要更多權力時就瓦解。Second第二，it sounds formal and a little grand它聽起來很正式、也有點氣派，so所以 journalists and writers often use it half-jokingly for smaller trios記者和作家常常半開玩笑地拿它來指比較小的三人組 ("the triumvirate that runs the school canteen")（像"the triumvirate that runs the school canteen"，管理學校餐廳的那三個人）。

It is countable: one triumvirate, two triumvirates. A member is a `triumvir`, though that word is now almost purely historical.

It它 is是 countable可數：one triumvirate, two triumvirates像one triumvirate、two triumvirates這樣變化。A member其中一個成員 is叫做 a `triumvir`triumvir，though不過 that word is now almost purely historical這個字現在幾乎只出現在歷史脈絡裡了。
