A person who has not yet been introduced or accepted into a particular group or activity.

Noninitiate → It is formed from "non-" (meaning not) and "initiate" (from Latin "initiare", meaning to begin or to start). The word "noninitiate" refers to someone who is not initiated or not a beginner in a particular context.
Think of 'non-' meaning 'not' and 'initiate' meaning 'to begin' — so a noninitiate is someone who has not begun or is not part of a certain group.
