brow

Compared meaning: eyebrow, the hair above the eye (noun).

比较义项：眉毛（名词）。

• eyebrow

  The everyday, neutral word for the eyebrow; central to the fixed idiom 'raise an eyebrow' (mild surprise or disapproval); the natural default choice in ordinary speech and writing.

  这是表示“眉毛”最常见、最中性的说法；是固定短语 raise an eyebrow（表示轻微的惊讶或不满）的核心用词；在日常口语和书面语中都是自然的默认选择。

  He raised an eyebrow when she mentioned quitting her stable job so suddenly.

  当她提到要突然辞去那份稳定的工作时，他挑起了眉毛。

• brow 本词

  A more literary or formal word for the eyebrow, typical of set phrases about sweat, effort or worry (furrowed brow, mop one's brow); it sounds unnatural in the 'raise an eyebrow' idiom.

  这是表示“眉毛”较为书面、文学化的说法，常见于表达汗水、努力或忧虑的固定搭配中（furrowed brow 皱眉、mop one's brow 擦汗）；用在 raise an eyebrow 这个习语里会显得不自然。

这两个词在这个义项上都表示“眉毛”，是一对容易混淆的近义词，但语气和使用场合不同：eyebrow 是日常、中性的说法，常用于固定短语 raise an eyebrow（表示惊讶或不满）；brow 更书面、文学化，常出现在 furrowed brow（皱眉）、mop one's brow（擦汗）这类固定搭配里。

• brow 本词

  A more literary or formal word, often paired with verbs like wipe, mop, or furrow, and common in descriptive writing rather than casual speech.

这两个词在“额头”这个意义上很接近，但语域不同：forehead 是日常口语中最常用、最中性的说法，brow 则更书面、略带文学色彩，常出现在描写皱眉、擦汗等动作的句子里。这里不比较 brow 表示“眉毛”（尤其复数 brows）或“山坡边缘”（the brow of a hill）的意思。
