Etymology
the term 'bump-and-run' is a modern english compound originating in the mid-20th century, primarily within american sports and finance jargon. it is a vivid example of a phrasal compound, where the literal, sequential actions of 'bumping' (making contact) and then 'running' (moving away swiftly) are metaphorically applied to abstract strategies. in football, it describes a permitted, immediate defensive contact followed by a pursuit; in finance, it metaphorically captures the action of artificially 'bumping' a stock's price before 'running' to sell. the term's logic relies entirely on the core anglo-saxon meanings of its component words, showcasing how english creates technical terminology through transparent, action-based imagery.
Analysis
this is a compound noun formed from three independent english words: 'bump' (to hit or knock), 'and' (a conjunction), and 'run' (to move quickly). it is not segmentable into bound morphemes.
