比较义项：管理人、看护人（名词）。

• keeper

  Emphasizes hands-on, everyday care and protection of a person, animal, or place; neutral-to-informal register, with little focus on legal or financial duty.

  强调对人、动物或场所进行日常的亲自照料和保护；语域中性偏口语，较少涉及法律或财务责任。

  The keeper at the zoo checks on the animals before closing time.

  动物园的管理员会在闭园前查看动物们的情况。

• steward

  Emphasizes managing someone else's property, resources, or affairs on their behalf, often in a formal or professional role; focused on administration and trust rather than physical protection.

  强调代表他人管理财产、资源或事务，往往是正式或专业的角色；侧重信托与管理，而不是亲自保护。

  The steward manages the family's finances while they are traveling abroad.

  这家人出国旅行期间，由管家负责打理家庭财务。

• custodian 本词

  Emphasizes formal or legal responsibility for something's safekeeping; in American English it is also the common word for a school building's caretaker.

  强调对某物的安全负有正式或法律上的责任；在美式英语中，这个词也常用来指学校楼宇的“管理员”。

  The custodian is legally responsible for locking up the school every night.

  保管员依法负责每晚将学校锁好。

Keeper, steward, and custodian all mean someone who cares for something, but they differ. Keeper stresses hands-on, everyday care of a person, animal, or place. Steward stresses managing someone else's property or affairs, in a formal role. Custodian stresses formal or legal responsibility for safekeeping.

这三个词都指“负责照管或看护某物或某人的人”，但语气和侧重不同：keeper 强调亲自照看和保护，steward 强调受托管理他人的财产或事务，custodian 强调负有正式或法律上的看管责任。这里不比较 keeper 的“守门员”义项，也不比较 steward 的“工会代表”义项。
