A person who does not engage in philosophy or is not trained in philosophical thought.
As a nonphilosopher, she found the discussions on metaphysics quite challenging.
Nonphilosopher → It is formed from "non-" (meaning not) and "philosopher" (from Greek "philosophos", meaning lover of wisdom). The word "nonphilosopher" refers to someone who is not a lover of wisdom or does not engage in philosophy.
Think of 'non-' meaning 'not' and 'philosopher' meaning 'lover of wisdom' — so a nonphilosopher is someone who is not engaged in the pursuit of wisdom.
