One thing that may help me keep them separate is the word within the word. PerMANent means something that can’t be removed. The actions of a MAN or a woMAN can enable things to be permanent. So put in the word man.

Permeant means something that can penetrate or saturate an object. This can often be through the pores. When a person is MEAN to others, their actions make a perMEANant effect on their victim’s life.
