Frequently Asked Questions

What is another word for instigator?
Instigator is most commonly used in a negative way to refer to a person who provokes other people or incites trouble—often by instigating arguments or encouraging dangerous actions. Synonyms include agitator, antagonizer, provocateur, troublemaker, incendiary, and firebrand. Some instigators make elaborate plans to stir up trouble, but others are opportunists who find any opportunity to throw a match on a powder keg. The term agent provocateur is more specific than provocateur. An agent provocateur is a secret agent working to incite people into illegal actions so that they can be arrested.
What is the opposite (antonym) of instigator?
The opposite of instigating is trying to stop trouble, rather than starting it. In the context of an argument or conflict, such a person might be called a peacemaker or peacekeeper. The word troubleshooter can also be used in this way. Mediators try to help parties in a conflict to resolve it.
Is instigator a negative word?
Instigator is almost always used in a negative way in the context of someone starting trouble. It’s possible to be used positively in a way that’s ironic, as in instigator of peace. In neutral contexts involving things causing other things, the neutral word catalyst is a good choice.
