substandard
UK: sʌbˈstændəd | US: sʌbˈstændərd
adj. below the usual or required standard
adj. inferior in quality or performance
The word "substandard" combines the Latin prefix sub- (meaning "under") with the English root standard (derived from Old French estandard, originally referring to a military banner as a symbol of authority or measure). Over time, standard evolved to denote an accepted benchmark of quality. By adding sub-, the term logically conveys "below the benchmark," reflecting its modern usage to describe inferior quality.
