This rope is no longer than that one. 这根绳子与那根绳子一样不长

Question

这句中的no longer 不是副词词性所表达的"不再"的含义 而是表达与"什么...比较"所以用的是比较级longer(原型long)
This rope is no longer(这个绳子不长 原型long) than that one(比那根)

这句有问题啊

no longer than指不超过，后面加长度或时间长度等，比如
The question must be no longer than( half a minute's duration), and can be asked only with the speaker's agreement.

The Greens believe Community financing under the CFP should be limited to vessels no longer than( 24 metres.)

你这句想表达的是不比那根长
应该是 not longer than,就是单纯的比较级否定句追问

可是我没找到 not longer这种结构啊

追答

否定词+比较级

不是固定搭配

这根绳子不比那根绳子长。
