What does fluctuation mean?
Fluctuation is continual change.
It’s a noun form of the verb fluctuate, meaning to continually change or shift back and forth.
Fluctuation is most commonly used in the context of abstract or intangible things that frequently change, such as temperature, the stock market, or someone’s mood.
Example: The fluctuation of the volume on my TV is really annoying—it gets louder during commercials and then it gets quiet again when the show comes back on.
Where does fluctuation come from?
The first records of the word fluctuation come from the 1400s. It ultimately comes from the Latin verb fluctuāre, meaning “to flow,” from fluctus, “a wave.”
Waves in the ocean are always in motion, rising, falling, going back and forth—they’re always in a state of fluctuation. Still, fluctuation is most commonly applied to nonphysical things. The amount of money in your bank account will fluctuate as you make deposits and withdrawals. Fluctuation may be predictable or unpredictable. In deserts, there is often an extreme but regular fluctuation in temperature between the day, when it’s very hot, and the night, when it can get very cold. But the fluctuation of a person’s mood—between happy and grumpy, for example—might happen much more unpredictably.
Things known for their fluctuation can be said to be in a state of flux—continuous change. (The word flux comes from the same root as fluctuation).
