In conclusion, "what to write" is a versatile and essential phrase for describing the selection of content or subject matter. Ludwig data confirms its high frequency across reputable news outlets like The New Yorker and The New York Times, as well as instructional platforms.

Whether you are facing writer's block or planning a formal report, this phrase is the standard way to address the choice of information to be conveyed.
