If you are adamant, you have made up your mind and you will not be talked out of it. “She was adamant that we leave at six.” It is about people and decisions, not about a hard door or a hard exam. Stronger than “sure,” a little more formal than “I won’t budge,” and common in news and grown-up talk. You can be adamant that something is true, or adamant that you will not do something. It often carries a little friction: someone hoped you would soften, and you did not.

If you are adamant如果你是 adamant, you have made up your mind就是你已經下定決心 and you will not be talked out of it而且不會被說服改變。“She was adamant that we leave at six.”像「“She was adamant that we leave at six.”」（她堅持我們六點就要走） It is about people and decisions這個字講的是人和決定, not about a hard door or a hard exam不是講堅硬的門或困難的考試。Stronger than “sure,”比「“sure”」（確定）語氣更強 a little more formal than “I won’t budge,”比「“I won’t budge”」（我不會讓步）正式一點, and common in news and grown-up talk在新聞和大人的對話裡很常見。You can be adamant that something is true你可以 adamant 地堅持某件事是真的, or adamant that you will not do something或堅持自己不會做某件事。It often carries a little friction它常常帶著一點小摩擦感: someone hoped you would soften有人希望你會軟化, and you did not但你沒有。

Though actually, the word is older than this use. Adamant was once a noun for a legendary stone so hard that nothing could cut it, and that is why the adjective feels like “hard as stone about this.” In everyday English the stone meaning has almost gone; we keep the stubborn-person meaning.

Though actually不過其實, the word is older than this use這個字比現在的用法還要古老。Adamant was once a noun for a legendary stoneAdamant 曾經是一個傳說中石頭的名詞 so hard that nothing could cut it硬到什麼都切不動它, and that is why the adjective feels like “hard as stone about this.”這就是為什麼形容詞給人的感覺像是「在這件事上硬得像石頭」 In everyday English the stone meaning has almost gone在日常英文裡，石頭的意思幾乎已經消失了; we keep the stubborn-person meaning我們保留的是「固執的人」這個意思。

The same old root also gave us diamond. You will still meet the stone in poems and fantasy, but if a teacher is adamant, she is not a jewel. She will not change her mind.

The same old root also gave us diamond同一個古老的字根也造出了 diamond（鑽石）這個字。You will still meet the stone in poems and fantasy你還是會在詩和奇幻故事裡碰到石頭的意思, but if a teacher is adamant但如果一位老師是 adamant, she is not a jewel她不是一顆寶石。She will not change her mind她是不會改變心意。
