Defiant → It is formed from "de-" (meaning down or away) and "fiare" (from Latin "fieri", meaning to make or to do). The word describes a person who is making a stand against authority or rules, hence showing resistance or boldness.
Think of someone who is 'making a stand' ('fiare') against something 'down' or 'away' ('de-') — that's why defiant means resisting authority.
