Expert writing Tips
Best practice
When using "fluctuated," ensure that the subject is something that can logically vary or oscillate. For instance, it's appropriate to say "prices fluctuated," but not "the building fluctuated."
Common error
Avoid using "fluctuated" when there is a clear upward or downward trend. "Fluctuated" implies irregular variation, not a consistent directional change. If prices consistently rose, do not say they fluctuated.
