A person who plans or plots something, often with dishonest or harmful intentions.
The villain was a true machinator, always scheming to achieve his goals.
Machinator → It is formed from "machinari" (meaning to contrive or devise) and the suffix "-tor" (meaning one who). The word "machinator" refers to one who devises or contrives plans, often with a sense of scheming or plotting.
Think of someone who 'devises' ('machinari') plans — that's why a 'machinator' is someone who creates schemes.
