scabby

the word 'scabby' is formed from the noun 'scab', which denotes a crust that forms over a healing wound. the core concept of 'scab' originates from a proto-germanic root related to itching and scratching, reflecting the irritating nature of such skin conditions. the adjectival suffix '-y', of old english origin, is appended to indicate the characteristic of being covered with or resembling scabs. over time, the term acquired a figurative sense, describing something or someone as morally low or contemptible, drawing a parallel between physical repulsiveness and ethical deficiency.

Structure: scab (crust) + y (adjective suffix) scab (from middle english 'scabbe', from old norse 'skabb', meaning itch, scab, related to old english 'sceabb' and latin 'scabies' meaning roughness, itch) + y (from old english '-ig', a suffix forming adjectives meaning "having the quality of").
