Not having experience or knowledge in a particular area; lacking training or familiarity.

Unversed → It is formed from "un-" (meaning not) and "versed" (from Latin "versare", meaning to turn or to be familiar with). The word "unversed" means not familiar or not skilled in a particular area.
Think of someone who is 'not' ('un-') familiar with something — that's why unversed means lacking knowledge or skill in that area.
