Shotty is a colloquial variant of shoddy (possibly influenced by 'shot' in the sense of worn-out); shoddy itself is of obscure 19th-century origin, originally meaning woolen yarn made from shredded rags. Older glosses in the chain include "shot", which help explain the semantic range of the modern word. Morphologically, shotty is best read as uncertain formation, yielding an English adjective shaped by both form history and later usage. In current English it functions as an adjective, with the sense "of poor quality or unreliable (slang variant of shoddy)". related forms include shoddy. The result is an English adjective whose etymology preserves the older forms while supporting the word's specialized modern meaning.
