• defined 本词

  Almost always used as a past participle (often with 'clearly'), stressing that the limits, scope, or responsibilities of something have been explicitly set out, not just easy to follow.

  几乎总是以过去分词形式使用（常与 clearly 搭配），强调某事物的界限、范围或职责已被明确规定，而不仅仅是容易理解。

  Each team member's responsibilities are clearly defined in the contract.

  合同中明确规定了每个团队成员的职责。

Clear and defined both describe something easy to understand. Clear is a general word used for instructions, ideas, or sounds that are easy to follow. Defined is almost always used as 'clearly defined', stressing that the limits or responsibilities of something have been explicitly set.

这两个词都形容事物容易理解，但 clear 更口语、通用，可用于说明、思路、声音等多种事物；defined 强调边界、范围或职责被明确划定，常用于角色、条款、目标等抽象事物，且几乎总以过去分词（defined / clearly defined）形式出现，很少作独立形容词使用。
