claim

Compared meaning: a demand for something (noun).

比较义项：要求（名词）。

• call

  Call as a demand almost always appears in the pattern "a call for something" (often an abstract change or action) - a public or collective appeal, milder and more general than a formal claim to a specific thing.

  作为“要求”，call 几乎总是以“a call for something”的固定搭配出现（后接抽象的变革或行动），是一种公开的、集体性的呼吁，比针对具体事物的正式索取（claim）更温和、更笼统。

  The workers issued a call for better safety conditions after the accident.

  事故发生后，工人们发出了改善安全条件的要求。

• claim 本词

  Claim is a demand for a specific thing the speaker believes they are entitled to, such as money, a prize or compensation, typically made formally to an institution like an insurer or organizer.

  claim 是对某项具体事物（如金钱、奖品、赔偿）的要求，说话人认为自己理应获得该物，通常是向保险公司、主办方等机构正式提出的索取。

  She filed a claim for a refund after the flight was cancelled.

  航班取消后，她提出了退款要求。

Call and claim can both mean a demand for something. Call is a public, general appeal for change. Claim is a formal demand for a specific thing, like money, that one feels entitled to. Call's other senses and claim's 'assert' sense are not compared.

这两个词都可以表示“要求”，但语气和用法不同：call 多用于“a call for something”这一固定搭配，指公开、集体性的呼吁，语气较温和笼统；claim 则指对具体事物（金钱、奖品、赔偿等）的正式索取，暗示说话人认为自己理应获得。这里不比较 call 的“打电话”“称呼”等义项，也不比较 claim 的“声称、断言”义项。
