fire-fighting

The compound "fire-fighting" is a transparent modern English formation. Its first element, "fire," descends from the Proto-Germanic fōr, a term for the visible effect of combustion. The second element, "fighting," originates from the Proto-Germanic fehtan, meaning to struggle or combat. The compound logically combines these two concepts to denote the specific struggle against destructive fires. This literal sense, emerging with organized fire brigades in the 18th and 19th centuries, has since extended metaphorically to describe any urgent effort to control a crisis.
