Use "viable subject" when you want to emphasize that something is not just possible, but also practical and likely to succeed as a focus of attention or activity. For example, "a viable subject for a documentary" suggests the topic is not only interesting but also has enough material to create a successful film.
Common error
Avoid using "viable subject" in contexts where a simpler term like "topic" or "subject matter" would suffice. Overusing the term can make your writing sound unnecessarily formal or verbose. "Topic", "subject matter", or "area of concern" are often more direct and appropriate.
