Etymology
Derived from Latin fluctuare (to wave, undulate), from fluctus (a wave), which itself comes from fluere (to flow). The root fluct- reflects motion or instability, while -ing marks the present participle form in English. The word vividly captures the idea of something moving like waves—unpredictable and dynamic.
