Expert writing Tips
Best practice
Pair it with negative verbs like "decline to" or "refuse to" in journalistic writing to indicate a lack of transparency or official silence.
Common error
A frequent mistake is omitting the preposition "on" and saying "comment what". In English, the verb "comment" is intransitive when used this way and requires "on" or "about" to link to the object of the remark.

Ludwig's WRAP-UP
The phrase "comment on what" is a robust and essential component of modern English, primarily used to direct focus toward a specific topic of discussion. As shown in Ludwig AI, it is the standard way to frame reactions in journalism and research. Its grammatical structure is stable, though it strictly requires the preposition "on" to remain correct. Whether used to decline an interview or to request student feedback, it provides a clear, functional link between the act of commenting and the specific information being judged. Using alternatives like "remark on what" can provide variety, but the main query remains the most versatile choice for neutral reporting.
