callous

The word "callous" paints a picture of emotional hardness. Originally, it described the thickened skin on someone's feet from repeated friction—a protective layer formed over something sensitive. Over time, this physical image extended to describe a similar hardening of the heart. To be callous is to be emotionally insensitive, showing a blatant disregard for the feelings or suffering of others.

It's stronger than simply being rude; it implies a deliberate indifference, an inability – or unwillingness – to understand or share someone else's pain. A callous remark might dismiss someone's grief, while a callous decision could prioritize profit over people's well-being.

You might encounter "callous" in descriptions of villains ("a callous dictator"), difficult situations ("the callous indifference of the bureaucracy"), or personal interactions ("his callous disregard for her feelings"). It often suggests a lack of moral fiber and an absence of empathy. While someone can be unintentionally insensitive, "callous" usually implies a degree of awareness about the impact of one's actions – and a choice to proceed regardless.

So, when you describe someone as callous, you're not just saying they lack feeling; you're suggesting a hardened emotional state that allows them to act without compassion or concern for others.
