What does callused mean?
Callused means covered with calluses — patches of thickened, hardened skin that develop where friction or pressure is repeatedly applied, such as on a laborer's hands or a musician's fingertips. The word can also be used figuratively to describe a person who has become emotionally hardened or less sensitive after enduring hardship repeatedly, as in a critic grown callused to harsh reviews. It functions primarily as an adjective and as the past form of the verb 'to callus', meaning to form such hardened tissue. Both spellings, 'callused' and 'calloused', are accepted, though they should not be confused with the purely emotional sense captured by the adjective 'callous'. Rich in physical and metaphorical resonance, the word evokes resilience, labor, and the body's remarkable ability to protect itself against wear.

Etymology of callused
Callused derives ultimately from the Latin noun 'callus' (also written 'callum'), meaning hard, thickened skin. English borrowed 'callus' directly in the sixteenth century as a term in anatomy and medicine, and the adjective 'callous' followed shortly afterward. The verb 'to callus', describing the process of forming hardened tissue, gave rise to the participle 'callused'. Related forms include 'callosity', a formal medical term for a callus.

The figurative sense overlaps with 'callous', though 'callous' carries a stronger connotation of deliberate insensitivity, while 'callused' suggests hardening acquired gradually through experience.
Easily confused with callused
