Why this word is great
PROVOCATEUR — [Noun] A person who deliberately behaves provocatively or acts as an undercover agent to incite others to illegal actions. From French provocateur, from Latin prōvocātor ("challenger, inciter"), from prōvocāre ("to provoke") + -tor (agent suffix). Unlike "instigator" (a neutral term for any initiator) or "agitator" (an open rabble-rouser), the provocateur thrives in shadows, wielding deception like a stiletto. It is the police informant nudging protesters toward violence, the anonymous forum poster seeding conspiracy with a wink, the charming stranger at the bar who just happens to steer the conversation toward revolt—a reminder that the most dangerous flames are often lit by hidden hands.
