How Do You Spell Callusing?
Answer. Callus/ CallousThese words appear to be the same, but they are not. A callus is a rough patch of skin on the skin's surface. Callous, an adjective meaning "insensitive to the feelings of others," is formed by adding an o for "offensive." Callus and callous share a Latin root that means "hardened," but callus is a noun and the word callous is an adjective.
