bodyguard

Compared meaning: a person who protects someone's safety (noun).

比较义项：护送、保护他人安全的人（名词）。

• escort

  Broader: anyone (often security staff, police, or an official) who accompanies and protects a person while moving through a place; emphasizes the act of accompanying, not a fixed job title.

  范围更广：指陪同某人穿行某地并加以保护的人（常是保安、警察或官方人员），强调“陪同护送”这一行为，而非固定的职业身份。

  Security agreed to escort the singer through the crowd to her car.

  保安同意护送这位歌手穿过人群到她的车边。

• bodyguard 本词

  Narrower: a person hired specifically and continuously to protect one individual from harm; implies a professional role, often armed and always present.

  范围更窄：特指专门、长期受雇保护某一个人人身安全的人，带有职业身份的含义，通常持械且随时在场。

  The singer hired a bodyguard to protect her at every concert.

  这位歌手雇了一名保镖，在每场演唱会上保护她。

Escort and bodyguard both mean a person who protects someone. Escort is broader: security staff, police, or others who accompany and protect a person while moving. Bodyguard is narrower: a person hired specifically to protect one individual from harm, implying a professional job.

两者都指负责保护某人人身安全的人，但 escort 强调“陪同护送”的动作，范围更广，不一定是专职保安；bodyguard 特指受雇专门贴身保护某人的保镖，是一种职业身份。escort 的其他义项（如“护送车队、社交陪同”）这里不作比较。
