Etymology
the word "fallout" is a modern compound formed from two ancient english elements. it originated in the mid-20th century within the context of nuclear physics, describing radioactive particles that "fall out" of the atmosphere following an explosion. the literal, physical sense of descent ("fall") combined with dispersal ("out") provided a vivid and logical description of the phenomenon. this concrete meaning was later extended metaphorically to describe the secondary, often negative, consequences of any significant event, which "fall out" or result from it.
