Etymology

volatility = volat<fly> + ility<noun suffix>

  • volat (from Latin volare, meaning "to fly") → Reflects rapid movement or change.
  • ility (noun-forming suffix from Latin -ilitas) → Indicates a state or quality.

Etymology Origin:
The word traces back to Latin volatilis ("fleeting, flying"), derived from volare ("to fly"). It originally described things that could fly or evaporate quickly (e.g., birds, gases). Over time, it expanded metaphorically to describe unpredictability in behavior, finance, and science—capturing the "flightiness" of change.
