Forehead and brow both name this part of the face, but differ in style. Forehead is the plain, everyday word, used in ordinary speech and medical contexts. Brow is more literary or formal, often used with verbs like wipe, mop, or furrow in descriptive writing.

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。
