瘦的近义词用英语可以用 "thin" 或 "spm"。
"Thin" 是源自古英语 "þynne" 的形容词，意思是身体细长或不够粗壮。例如：
She has a thin face and long, thin fingers. (她有一张瘦小的脸和长长的细手指。)
The cat is thin because it hasn't been eating enough. (这只猫很瘦，因为它没吃够。)
"Spm" 是源自中古英语 "slym" 的形容词，意思是身体细长或苗条。例如：
She looks spm in those jeans. (她穿这条牛仔裤看起来很苗条。)
He's very spm for his height. (他很瘦，而且很高。)
两个词都可以用来形容人或动物的体型，但 "thin" 通常指的是身体整体不够粗壮，而 "spm" 则更多用来形容身体的某一部分（通常是腰部或腹部）纤细或苗条。
