To furnish with new or modified parts or equipment not available at the time of original manufacture; to update or modernize.
Compound word from retro- 'backward' + fit, coined in the 1940s in aviation contexts. Originally described updating aircraft with newer equipment, then expanded to buildings, cars, and technology.
Retrofitting represents humanity's refusal to accept obsolescence - instead of discarding the old, we ingeniously adapt it for new purposes. From earthquake-proofing old buildings to adding USB ports to vintage cars, retrofitting bridges the gap between nostalgia and progress.
