Expert writing Tips

Best practice

When describing data or measurements, use "fluctuate across" to emphasize that values are not constant and exhibit variations, but not necessarily random ones. Be mindful of the context, as this phrase is suited to describe changes that may show some level of predictability (hormone levels, for example).

Common error

Don't use "fluctuate across" when you mean completely random or unpredictable variation. This phrase implies some level of pattern or influence affecting the changes, so if the variation is truly random, use terms like "vary randomly" or "change erratically" instead.

Linguistic Context

The phrase "fluctuate across" functions as a verb phrase indicating that something varies or changes over a particular range or domain. Ludwig AI confirms its usability and correctness in written English.
