An insulting word for someone who does not know things that most people around them know — and, usually, who is confident anyway. That second part is why people choose this word instead of just 'he doesn't know'.

An insulting word這是一個罵人的字 for someone用來說某個人 who does not know things不知道那些事 that most people around them know周圍大多數人都知道的 — and, usually而且通常, who is confident anyway還一副很有自信的樣子。That second part後面那部分 is why people choose this word正是為什麼大家會選這個字 instead of just 'he doesn't know'而不是只說「他不知道」。

It carries a sneer, and it makes the speaker sound a bit grand, so it often lands as old-fashioned or mock-formal. You will see it in angry newspaper columns, in comment sections, and in comedy.

It carries a sneer它帶著一絲嘲諷, and it makes the speaker sound a bit grand也讓說話的人聽起來有點自命不凡, so it often lands as old-fashioned or mock-formal所以常給人一種老派或假裝正式的感覺。You will see it你會看到它 in angry newspaper columns, in comment sections, and in comedy在氣呼呼的報紙專欄、留言區和喜劇裡。

Because it sounds pompous, English speakers frequently use it about themselves, as a joke and a way of being modest: 'I'm a complete ignoramus when it comes to cars.' That self-mocking use, often with 'a complete / total ignoramus about ___', may be the most common one in real speech, and it is quite friendly. Aimed at another person, though, it is a real insult.

Because it sounds pompous正因為它聽起來自大, English speakers frequently use it about themselves英語使用者反而常拿它自嘲, as a joke and a way of being modest當笑話也當一種謙虛的方式: 'I'm a complete ignoramus when it comes to cars.'『I'm a complete ignoramus when it comes to cars.』（講到車子我完全是個外行。） That self-mocking use這種自嘲用法, often with 'a complete / total ignoramus about ___'常搭配『a complete / total ignoramus about ___』, may be the most common one in real speech可能是實際說話裡最常見的用法, and it is quite friendly而且相當友善。Aimed at another person不過如果是拿來說別人, though, it is a real insult那就是真的在罵人了。

The plural is 'ignoramuses'. Do not write 'ignorami' — it looks Latin, but the original word was not that kind of noun, so that plural is a joke form only.

The plural is複數是 'ignoramuses''ignoramuses'。Do not write不要寫成 'ignorami''ignorami' — it looks Latin它看起來很拉丁文, but the original word was not that kind of noun但原本這個字並不是那種名詞, so that plural is a joke form only所以那個複數形式只是個玩笑說法。
