shabby

The word 'shabby' originates from the Old English word for 'scab', sceabb. This root evolved to describe the rough, scaly, or diseased appearance of skin, which metaphorically extended to mean anything in a worn, threadbare, or deteriorated condition, much like fabric that is frayed and rough. By the 17th century, with the addition of the adjectival suffix '-y', it solidified its modern meaning, primarily describing objects or clothing showing signs of age and neglect. The further semantic shift to describe mean or contemptible behavior draws on the metaphor of something being morally "worn out" or inferior.
