Expert writing Tips

Best practice

Avoid using the passive voice with intransitive verbs like 'fluctuate'. Instead, use active constructions (e.g., "prices fluctuate") or rephrase using a different verb or noun form.

Common error

Do not use "is" with "fluctuated" as if forming a passive construction. "Fluctuate" typically describes an action performed by something, not done to it. A correct usage would be "prices are fluctuating", using the present continuous tense.

Linguistic Context

The phrase "is fluctuated" is an incorrect attempt to use the verb 'fluctuate' in a passive construction. As Ludwig AI highlights, 'fluctuate' is typically used as an intransitive verb, meaning it does not take a direct object and cannot be used in the passive voice.
