integral

Compared meaning: being a natural, built-in part of something (adjective).

比较义项：作为某事物固有的、自然的一部分（形容词）。

• inherent

  Describes a natural trait or quality something has by nature, often paired with nouns like "risk" or "trait"; does not imply the thing is a required part of a larger whole.

  描述某事物天生具有的特质或性质，常与“风险”“特质”等词搭配；并不表示该事物是整体中必不可少的组成部分。

  There is an inherent risk in investing in the stock market.

  投资股市存在固有的风险。

• integral 本词

  Emphasizes being a necessary, essential component of a larger whole or system, commonly used as "integral to" or "integral part of"; removing it would leave the whole incomplete.

  强调是更大整体或系统中不可或缺的组成部分，常用“integral to”或“integral part of”结构；去掉它整体就不完整。

  The heart is an integral part of the circulatory system.

  心脏是循环系统中不可或缺的一部分。

• intrinsic

  A more formal term for a quality belonging to something's essential nature, independent of outside factors; often contrasted with "extrinsic" and paired with "value" or "motivation".

  较正式的用词，指属于事物本质、不受外部因素影响的特质；常与“extrinsic（外在的）”相对，并与“value”“motivation”等词搭配。

  Money was never her intrinsic motivation for helping others.

  金钱从来不是她帮助他人的内在动机。

All three describe a natural quality something has. Inherent often pairs with risk or trait. Intrinsic is more formal, contrasted with extrinsic, and pairs with value or motivation. Integral means a necessary part of a whole. Its math sense is not compared here.

这三个词在这个义项上都表示某事物本身固有、自然而然具备的特点，但语气和搭配不同：inherent 常用于“固有风险”“固有特质”等说法；intrinsic 语域更正式，常与 extrinsic（外在的）相对，多用于“内在价值”“内在动机”；integral 则强调是整体中不可或缺的组成部分，常用“integral to / integral part of”结构。这里不比较 integral 在数学中“积分的”这一义项。
