Compared meaning: to be unsure and delay acting or deciding (verb).

比较义项：犹豫，迟疑（动词）。

• hesitate

  Describes a brief pause right before doing or saying something, caused by uncertainty or nervousness; very common in the pattern 'don't hesitate to'.

  指在做某事或说某事之前因不确定或紧张而短暂停顿；常用于“don't hesitate to”这一固定搭配中。

  Don't hesitate to call me if you need any help moving.

  如果搬家需要帮忙，尽管给我打电话，不要犹豫。

• waver 本词

  Describes something already steady, such as a voice, opinion, or resolve, becoming unsteady and fluctuating; not a one-time pause but a loss of firmness over time.

  指原本稳定的东西，例如声音、看法或决心，开始变得不稳定、摇摆不定；不是一次性的停顿，而是稳定性随时间逐渐动摇。

  Her voice began to waver as she talked about the accident.

  她说起那场事故时，声音开始变得颤抖不稳。

Hesitate and waver both mean being unsure. Hesitate describes a short pause before doing something, from uncertainty or nerves, as in 'don't hesitate to ask.' Waver describes something already steady, like a voice or opinion, becoming unsteady over time, not just a brief pause.

这两个词都表示“犹豫、迟疑”，但 hesitate 侧重行动前的短暂停顿，waver 侧重已有的想法、声音或决心变得不稳定、摇摆不定。两词没有其他需要排除的义项。
