shitty

the word "shitty" is a modern english compound formed from the native germanic noun "shit" and the productive adjectival suffix "-y". the root "shit" traces back to proto-germanic skit- and further to proto-indo-european skeyd- meaning 'to cut, split, divide', a reference to the act of defecation. the suffix "-y", from old english -ig, is a common means of deriving descriptive adjectives from nouns, indicating possession or character. thus, the literal construction "full of shit" evolved from its concrete, physical sense to a widely used slang term denoting anything of low quality or unpleasant condition, demonstrating a typical path of semantic pejoration and generalization.

Structure: shit (excrement) + y (adjective-forming suffix) "shit" (from old english scitte, meaning 'dung, excrement', of germanic origin); "y" (a native english suffix forming adjectives, meaning 'characterized by; full of').
