Nonclerical → It is formed from "non-" (meaning not) and "clerical" (from Latin "clericalis", meaning relating to a clerk or clergyman). The word "nonclerical" means not related to or characteristic of clerks or clergy.
Think of 'non-' meaning 'not' and 'clerical' relating to clerks or clergy — so nonclerical refers to something that is not related to clerks or clergy.
