the term "stop-and-go" is a modern english compound adjective derived directly from the phrasal verb "to stop and go". it follows a common pattern in english where a descriptive phrase is hyphenated to function as a single modifier. the logic is entirely literal and transparent, describing a process or movement that alternates between halting and proceeding. its primary application to traffic patterns emerged in the mid-20th century with the rise of congested automobile travel, and it has since been extended metaphorically to describe any intermittent or halting process. the construction relies on the core anglo-saxon verbs "stop" (from old english stoppian, meaning to block up) and "go" (from old english gān, meaning to proceed).

this is a compound adjective formed from the phrasal verb "stop and go". it is not segmentable into classical morphemes as it is a modern english syntactic construction.
