Yuppie and yuppify are products of the 1980s, but they owe a debt to predecessors from decades prior. Hippie (referring to a long-haired, unconventionally dressed young person who rejects societal mores; from hip, meaning "cool") first appeared in print in the 1950s. Yippie (naming a politically active hippie; from Youth International Party) followed hippie a decade later. Gentrification and gentrify (both of which have to do with the effects of influxes of relatively affluent people into deteriorating neighborhoods; from gentry) then evolved. Yuppie (pointing out a young well-paid professional who lives and works in or near an urban area; probably from young urban professional, influenced by hippie and yippie) hit the press in the early 1980s, bringing along yuppify and yuppification (patterned after gentrify and gentrification).
