Unalterable means it cannot be changed. It is stronger and more final than 'fixed' or 'permanent', because it says changing is not merely difficult but impossible — the door is shut.

Unalterable means it cannot be changed意思是不能被改變。It is stronger and more final than 'fixed' or 'permanent'它比 'fixed' 或 'permanent' 更強烈、更絕對, because it says changing is not merely difficult but impossible因為它說的不是難改,而是根本不可能改 — the door is shut門已經關死了。

You meet it with facts, rules, laws, decisions, and the past: an unalterable fact, an unalterable law of nature, an unalterable decision, the unalterable past. It also attaches to firm human qualities — unalterable opposition, an unalterable belief — where it means the person will not be moved no matter what you say.

The word is formal and rather grand; it belongs to law, philosophy, contracts, religion, and serious writing, and it sounds heavy in ordinary conversation, where people say 'can't be changed' or 'final'.

The word is formal and rather grand這個字很正式,語氣也頗大; it belongs to law, philosophy, contracts, religion, and serious writing屬於法律、哲學、合約、宗教和嚴肅文章的用字, and it sounds heavy in ordinary conversation日常對話裡聽起來會很重, where people say 'can't be changed' or 'final'一般人會說 'can't be changed' 或 'final'。

Two things worth noticing. First, unalterable often carries feeling, not just fact: calling a decision unalterable can be a way of ending an argument, and a listener may hear stubbornness rather than impossibility. Second, alter is a slightly narrower word than change — it suggests adjusting something that stays basically itself, the way a tailor alters a jacket. So unalterable leans towards 'you cannot adjust even a detail of it', which is part of why it feels so absolute.

Two things worth noticing有兩件事值得注意。First, unalterable often carries feeling, not just fact第一,unalterable 常常帶著情緒,不只是陳述事實: calling a decision unalterable can be a way of ending an argument把一個決定說成 unalterable,可能是想結束爭論, and a listener may hear stubbornness rather than impossibility聽的人感受到的可能是固執,而不是真的不可能。Second, alter is a slightly narrower word than change第二,alter 比 change 意思窄一點 — it suggests adjusting something that stays basically itself它暗示調整的東西本質上還是原來那個, the way a tailor alters a jacket就像裁縫師修改一件外套那樣。So unalterable leans towards 'you cannot adjust even a detail of it'所以 unalterable 更偏向「連一個細節都不能調整」, which is part of why it feels so absolute這也是它聽起來這麼絕對的原因之一。
