  抱歉，你能再说一遍吗？我没听清你的名字。

• reiterate

  A formal word implying you say a point again for emphasis, so listeners remember or take it seriously; used for statements already made, never for physical actions.

• restate 本词

  A formal word implying you say something again using different or clearer wording, usually to remove confusion; not an exact word-for-word repetition.

  正式用词，表示换一种说法、说得更清楚，通常是为了消除误解；不是逐字重复原话。

  Could you restate the instructions in simpler words? I'm still confused.

  你能用更简单的话把说明再说一遍吗？我还是不太明白。

Repeat, reiterate and restate all mean to say something again, but differ in tone. Repeat is common and neutral, often when a listener didn't hear. Reiterate is formal, repeating a point for emphasis. Restate is formal too, saying something again with clearer wording.

这三个词都表示把说过的话再说一次，但语气和语域不同：repeat 最中性、最常用；reiterate 强调为了强调重点而正式地重复；restate 强调换一种说法把话说得更清楚。这里不比较 repeat 表示“重复某个动作”的用法（如重复一遍动作或过程）。
