exclude

Compared meaning: to leave someone or something out (verb).

比较义项：把某人或某事物排除在外、不包括在内（动词）。

• exclude 本词

  Exclude stresses a deliberate, often rule-based act of keeping someone or something out of a group, place, or category; common with people and formal policies.

  exclude 强调有意地、常常基于规则地把某人或某事物排除在某个群体、场所或类别之外；常与人和正式规定搭配使用。

  The new rule will exclude students who arrive after nine.

  这项新规定将把九点以后到达的学生排除在外。

• except

  Except in this sense is used mainly as a preposition or conjunction, not as a full verb; it simply names the one item left out of an otherwise general statement.

  except 在这个意义上主要用作介词或连词，而不是完整的动词；它只是指出在一个普遍陈述中被排除在外的那一项。

  Everyone came to the party except my brother.

  除了我兄弟，大家都来参加了聚会。

• omit

  Omit means to leave something out or fail to include it, often unintentionally, especially details, items, or information in writing, lists, or forms.

  omit 指遗漏或未能包含某项内容，往往并非故意，尤其用于书写、清单或表格中的细节或信息。

  Please don't omit your phone number from the application form.

  请不要在申请表上遗漏你的电话号码。

All three mean not including someone or something. Exclude means deliberately keeping something out of a group by rule; formal. Except is mainly a preposition or conjunction (except for...), rarely a full verb. Omit means leaving something out of writing or a list, often unintentionally.

这三个词都表示“不包括某人或某事物”，但语气和搭配不同：exclude 强调有意地、常常基于规则地把人或事物排除在某个群体、场所或范围之外，语气较正式；except 在这个意义上几乎只用作介词或连词（except for…），很少作完整动词使用；omit 则常指在书写、清单或信息中遗漏某项内容，不一定是故意的。

Compared meaning: to stop someone from entering or doing something (verb).

比较义项：阻止某人进入或做某事（动词）。

• bar

  Bar stresses an official or authoritative prohibition that stops someone from entering a place or doing something, usually phrased as "bar someone from + entering/doing".

  bar 强调由权威或规定作出的正式禁止，阻止某人进入某地或做某事，常用“bar someone from + 进入/做某事”的结构。

  The judge barred him from entering the courthouse again.

  法官禁止他再次进入法院。

• exclude 本词

  Exclude focuses on leaving someone out of a group or category by a rule or condition, rather than an authority actively stopping them; the tone is more neutral and administrative.

  exclude 侧重根据规则或条件把某人排除在某个群体或范围之外，而不是强调有权威主动出面阻止；语气更中性、偏公文化。

  The new rule will exclude students who arrive after nine.

  这项新规定将把九点以后到达的学生排除在外。

Bar and exclude both mean to stop someone entering or doing something, but the tone differs. Bar stresses an official ban. Exclude stresses leaving someone out based on a rule, in a neutral, formal tone. Bar's noun meaning, 'a pub', is not compared.

这两个词在“阻止某人进入或做某事”这一意义上比较接近，但语气不同：bar 强调有权威或规则明令禁止，语气较重；exclude 强调依据规则或标准把某人排除在某个范围之外，语气更中性、偏书面。这里不比较 bar 作名词表示“酒吧”的用法。
