Key Differences

"Callous" and "Callus" are two words that, while sounding similar, represent distinct concepts. "Callous" typically describes a person or behavior characterized by a lack of empathy or emotional sensitivity. In contrast, "Callus" refers to a physical condition where the skin thickens due to repeated friction or pressure.
When one exhibits a "Callous" attitude, they might seem indifferent to the feelings or needs of others. This can be through words, actions, or simply a lack of response. On the other hand, a "Callus" can be a result of manual labor, playing musical instruments, or any activity that applies consistent pressure to the skin.
"Callous" can often have negative connotations, implying that an individual is cold-hearted or uncaring. Meanwhile, having a "Callus" might be seen as a badge of hard work or dedication to a particular craft or activity.
In literature, a "Callous" character may be depicted as a villain or someone with a hardened heart. In contrast, "Callus" might be used in descriptions to showcase a character's labor-intensive lifestyle or profession.
While "Callous" is more abstract and pertains to feelings and attitudes, "Callus" is tangible, relating to a visible and touchable condition on the skin.
