obdurate

The word obdurate describes someone or something that is stubbornly resistant to change, influence, or persuasion. It goes beyond simple stubbornness; it suggests a hardened inflexibility, often accompanied by a lack of empathy or compassion. An obdurate person isn't just disagreeing with you—they are actively refusing to consider your point of view, even in the face of compelling evidence or heartfelt pleas.

The origins of obdurate lie in Latin, stemming from words meaning "to harden" or "become tough." This etymology helps explain why it's often used to describe someone who has become emotionally hardened over time, perhaps through difficult experiences. Think of a heart that has grown calloused and resistant to feeling.

You're likely to encounter obdurate in more formal writing—literature, historical accounts, or philosophical discussions. It isn't something you'd typically use in casual conversation. For example: "Despite the overwhelming evidence of his guilt, the defendant remained obdurate, refusing to confess." Or, "The obdurate bureaucracy made it nearly impossible for small businesses to obtain permits."

It can also describe things that are difficult to penetrate or overcome—an obdurate problem, a seemingly insurmountable obstacle. But most often, it's used to paint a portrait of someone unyielding in their beliefs or actions, someone who is determined to hold fast to their position regardless of the consequences. So if you meet someone truly obdurate, prepare for a challenge—changing their mind will be no easy feat!
