VOCAB BUILDER

What does fluctuant mean?

Fluctuant is an adjective used to describe things that are fluctuating—continually changing or shifting back and forth. It often implies that such things are unstable or prone to varying.

It’s typically applied to abstract or intangible things that frequently change, such as temperature, the stock market, or someone’s mood.

It can also be used to describe things that move or seem to move in waves.

Fluctuant is much less commonly used than the verb fluctuate and the noun fluctuation.

Example: The volume on my TV is annoyingly fluctuant—it gets louder during commercials and then it gets quiet again when the show comes back on.

Where does fluctuant come from?

The first records of the word fluctuant come from the 1500s. It comes from the Latin verb fluctuāre, meaning “to undulate” or “to flow,” from fluctus, “a wave.”

Waves in the ocean are always in motion, rising, falling, going back and forth—they’re fluctuant. Still, fluctuant is perhaps most commonly applied to nonphysical things. The amount of money in your bank account is fluctuant—it’s always going up and down as you make deposits and withdrawals. Things described as fluctuant may experience fluctuation that’s predictable or unpredictable. The temperature in deserts is fluctuant, often regularly fluctuating between the day, when it’s very hot, and the night, when it can get very cold. If a person’s mood is described as fluctuant, it’s probably unpredictable.

Things that are fluctuant can be said to be in a state of flux—continuous change. (The word flux comes from the same root as fluctuant).
