Synonym discussion
Sense: adjective/1
Calloused is the most specific of these words because it refers to skin that has become thick and hard from repeated rubbing or hard work. Hardened is broader and can describe skin, attitudes, metal, or other materials, so it does not automatically suggest raised patches of skin. Rough often describes a surface that does not feel smooth, but rough skin may simply be dry or uneven rather than thickened into calluses. Toughened emphasizes increased strength or resistance, especially after training or repeated use, and may be used for both people and materials. If a guitarist has calloused fingertips, the focus is on the hard skin itself; if training has toughened her hands, the focus is on increased resistance to pain or damage.
Common collocations
Etymology
Calloused comes from the noun and verb callus, which ultimately goes back to Latin callum or callus, meaning thick or hardened skin. The adjective adds the -ed ending to describe skin that has developed those hard patches through repeated pressure or rubbing.
