比较义项：犯小错误、出错（动词）。

• slip

  Informal, describing a small, usually unintentional lapse in speech, memory or behaviour; suggests something momentary and forgivable, not a serious error.

  较为口语化，指言语、记忆或行为上一次短暂、无意的小失误，给人一种可以原谅、不算严重的感觉。

  She slipped and called her new boss by her ex's name.

  她一时说错，把新老板叫成了前男友的名字。

• err 本词

  More formal or literary, meaning to make a mistake or misjudgement; often paired with 'on the side of' and can imply a broader or more serious wrongdoing.

  较为正式或书面化，意为犯错误或判断失误，常见于固定搭配（err on the side of caution，宁可…也要…），也可能暗指范围更广或更严重的过错。

  The judge admitted he had erred in his ruling.

  法官承认自己在裁决中犯了错误。

Slip and err both mean to make a small mistake. Slip is informal, describing a small, unintentional lapse in speech or memory that is easy to forgive. Err is more formal and literary, often used in the phrase 'err on the side of caution'.

这两个词在犯错这一义项上意思相近，但语气不同：slip较为随意、口语化，指无意间的小失误；err更正式、书面化，常出现在err on the side of caution这样的固定搭配中，语气更严肃。这里不比较slip的其他常见义项（如滑倒）。
