Unexpert → It is formed from "un-" (meaning not) and "expert" (from Latin "expertus", meaning experienced or skilled). The word "unexpert" means not experienced or lacking expertise.
Think of 'not' ('un-') being added to someone who is 'skilled' ('expert') — that's why unexpert means lacking skill or experience.
