Etymology

Origin of callous

First recorded in 1375–1425; late Middle English from Latin callōsus “hard-skinned, tough,” equivalent to call(um) “tough skin, any hard substance” + -ōsus -ous

Explanation

A callous person is insensitive or emotionally hardened. If you laugh at your little sister while she's trying to show you her poetry, you're being callous. Callous comes from the Latin root callum for hard skin. If you walk barefoot a lot, your feet will become calloused. We often use callous, as an adjective or a verb, in the metaphorical sense for emotionally hardened. If someone is unmoved by other people's problems, you might say he shows a callous indifference to human suffering or that his heart has been calloused by his own problems.
