cf凤凰之息和高爆手雷:"There is a custom by which the young should respect the old."中为什么用"by which"?

实际上是respect the old by a custom (依据一个风俗) which 引导定语从句,从句中的介词可以放在which前面.

这是个定语从句,如果把by移到后面,这个句子就一目了然了
:There is a custom which the young should by respect the old .
version:依据风俗:年轻人应该尊敬老年人。

定语从句,老师应该会讲这类句子

这是个介词前置的定语从句,可分解成: There is a custom.By the custom (依据这个习俗)the young should respect the old .所以用by which
