hard-bitten

the compound 'hard-bitten' originates from early 20th century sporting jargon, specifically describing tough, seasoned horses that were difficult to manage due to having been bitten hard on the bit. the term 'hard' conveys severity and resilience, while 'bitten' literally refers to the physical marking from the bit. this literal imagery of an animal toughened by harsh treatment was then figuratively extended to describe people, particularly journalists or soldiers, who have become callous and tenacious through enduring difficult circumstances. the evolution captures a vivid metaphorical shift from a concrete physical state to an abstract psychological quality.

Structure: hard (firm, severe) + bitten (wounded, affected) - hard: from old english 'heard', meaning "solid, firm, severe, difficult". functions as an intensifying adjective. - bitten: past participle of 'bite', from old english 'bitan', meaning "to cut or wound with teeth". functions metaphorically to indicate being affected or marked by an experience.
