• comparable 本词

  Weaker than the others; means only similar enough to be usefully compared, not actually the same; typically used with 'comparable to/in' for price, size, or quality.

  程度比其他几个词都弱，只表示“相似到可以拿来比较”，并不是真的相同；常用“comparable to/in”，多用于价格、大小或质量方面。

• duplicate

  Describes something made as an exact copy of a specific original, especially documents or keys; implies an original exists; typically placed before a noun like 'duplicate key'.

Same, identical, comparable, and duplicate all describe things with little or no difference. Same is the most general word. Identical is stronger, meaning every detail matches exactly. Comparable is weaker, meaning only similar enough to compare, not truly the same. Duplicate means an exact copy.

这几个词都表示“相同”或“相似”，但程度和用法不同：identical 强调完全一致、毫无差别；same 是最通用、语气最中性的说法；duplicate 特指按照原件制作的复制品；comparable 程度最弱，只表示“相似到可以拿来比较”，并非真正相同。这里不比较 duplicate 作名词（复制品）或动词（复制）的用法。
