Unlicensed → It is formed from "un-" (meaning not) and "licensed" (from Latin "licentia", meaning freedom or permission). The word "unlicensed" means not having permission or freedom to do something, particularly in a legal or official context.
Think of 'not' ('un-') having 'permission' ('licensed') — that's why unlicensed means not having permission.
