A turncoat is someone who abandons the side they belonged to and joins the other side. It is used most about politics — a politician who leaves one party for the party they used to attack — but it works for any group with two sides: a union, a company, a sports club, a group of friends in an argument.

A turncoat是 someone拋棄自己原本陣營、投靠另一邊的人 who abandons the side they belonged to and joins the other side. It最常 is used most about politics用在政治上 — a politician一個政治人物 who leaves one party for the party they used to attack離開原本的黨、投靠自己以前攻擊的黨 — but不過 it works for any group with two sides只要是分兩邊的團體都適用: a union工會, a company公司, a sports club運動俱樂部, a group of friends in an argument吵架中的一群朋友.

The word is always an insult. Nobody calls themselves a turncoat; it is what the people you left call you.

The word這個字 is always an insult永遠是罵人的話. Nobody沒有人 calls themselves a turncoat會自稱是turncoat; it是 is what the people you left call you是你離開的那群人拿來罵你的.

That is the heart of the word, and it is worth feeling the difference from its neighbours. A traitor is far heavier and suggests real betrayal, even a crime against your country. A defector is the neutral, news-report word for someone who leaves a country or an organisation, with no judgement attached. A turncoat sits between them, and carries a particular flavour of contempt: not "you are dangerous" but "you have no real beliefs, you go wherever it suits you".

That這 is the heart of the word就是這個字的核心, and而 it is worth feeling the difference from its neighbours值得感受它跟鄰近字的差別. A traitor叛國者 is far heavier重得多, and suggests real betrayal暗示真正的背叛, even a crime against your country甚至是對國家犯罪. A defector投誠者、脫離者 is the neutral, news-report word是中性的新聞用字 for someone who leaves a country or an organisation指離開一個國家或組織的人, with no judgement attached不帶評價. A turncoat這個字 sits between them介於兩者之間, and而且 carries a particular flavour of contempt帶著一種特定的輕視: not "you are dangerous"不是「你很危險」 but而是 "you have no real beliefs, you go wherever it suits you"「你沒有真正的立場，哪邊有利就去哪邊」.

It is a countable noun. There is an old adjective, turncoat, used before another noun in phrases like "a turncoat senator", and you may occasionally meet it as a verb, but neither is common — the noun is what you need.

In feel it is somewhat old-fashioned and literary, the kind of word a headline or a speech reaches for when it wants a good sharp hit. In everyday conversation people are more likely to say "he switched sides" or "he sold us out".

In feel感覺上 it is somewhat old-fashioned and literary有點過時、偏文學, the kind of word就是那種 a headline or a speech reaches for標題或演講會用的字 when it wants a good sharp hit想要一針見血時. In everyday conversation日常對話裡 people are more likely to say人比較會說 "he switched sides"「he switched sides」 or或 "he sold us out"「he sold us out」.
