OB-stuh-nut
(adjective) Stubbornly refusing to change one’s opinion or course of action.
Despite undeniable evidence, he remained obstinate in his belief that the earth was flat.
Fun Fact
“Obstinate” shares roots with the word “obstacle.” While it’s often negative, the trait has sometimes been admired in revolutionaries, inventors, and activists. Historical figures from Galileo to Rosa Parks were once described as obstinate for defying norms.
dawg-MAT-ik
(adjective) Asserting opinions or beliefs in an arrogant, rigid, and often unyielding way.
His dogmatic approach left no room for compromise or alternative ideas.
Mid 17th century: from late Latin dogmaticus, from Greek dogmatikos, from dogma ‘opinion, tenet’.
Fun Fact
Dogmatic is often used in politics, academia, or religion—anywhere someone clings to a belief system so tightly that opposing views are dismissed outright. It doesn’t necessarily mean the belief is wrong—just that it’s inflexibly held. In leadership or conversation, being called dogmatic is rarely a compliment; it suggests stubborn conviction without curiosity or tolerance.
