Unorthodoxly → It is formed from "un-" (meaning not), "orthodox" (from Greek "orthodoxos", meaning having the right opinion or belief), and "-ly" (meaning in a manner). The word "unorthodoxly" means in a manner that is not conforming to established beliefs or practices.
Think of 'not' ('un-') following beliefs that are 'correct' ('orthodox') — so when something is done 'unorthodoxly', it means it's done in a way that doesn't follow the usual beliefs.
