Inexpertly → It is formed from "in-" (meaning not) and "expert" (from Latin "expertus", meaning experienced or skilled) and the suffix "-ly" (meaning in a manner). The word "inexpertly" means in a manner that is not skilled or experienced.
Think of 'not' ('in-') being combined with 'skilled' ('expert') to remember that 'inexpertly' means doing something without skill.
