souped-up

the term 'souped-up' is a 20th-century american english slang formation. the verb 'to soup,' meaning to modify an engine for higher performance, likely emerged in the 1920s from the notion of 'supercharging' or, metaphorically, from 'soup' as something that invigorates or strengthens. the addition of the past participle '-ed' and the particle 'up' follows a common english phrasal verb pattern, creating an adjective that describes something enhanced to a state of greater power or elaborateness. its logic moves from the literal idea of injecting vigor (like nourishing soup) into a machine to the broader abstract sense of anything modified to be more impressive or intense.

Structure: soup (sense) + ed (sense) + up (sense) soup (from the verb 'soup', meaning to increase the power of, of uncertain origin, likely from 'supercharge' or 'soup' as a nourishing substance; functional role: root verb). ed (english past participle suffix; functional role: indicates a completed action or state). up (english adverb/particle; functional role: indicates an increase, enhancement, or completion).
