If you need an example of this read republic book 1.

Socrates essentially just dunks on these guys that are trying to define justice.

One of them says that justice is doing good to your friends and evil to your enemies

The way that socrates reubuts this argument is that the fella in question doesn’t define friends, enemies, good, or evil, so how can he expect to come up with an idea of what justice is before first defining these other concepts that are meaningful to us because of their common usage, but can be twisted greatly in logical argumentation.
