Which of these best defines the term 'Theme' in writing?

Defining 'Theme' in writing is best captured by understanding it as the overall message of the text. A theme is the central idea or underlying message that the author conveys through the narrative, characters, and events within a work. It often reflects universal truths or insights about life, society, or human nature, allowing readers to gain a deeper understanding of the text's meaning.

This contrasts with supporting details, which help to build and substantiate the theme but do not define it. The purpose of writing is related but refers more to why the author wrote the text in the first place, encompassing broader intentions rather than the specific message conveyed. Similarly, using colorful language pertains to the style and techniques an author employs to enhance their narrative but does not directly relate to the core theme itself. Thus, the overall message is fundamental in encapsulating what the theme truly represents in literature.
