explain the difference between theme & central idea.

Theme refers to the underlying message or main idea that runs throughout a piece of literature or work of art. It is a broader concept that can be applied to various aspects of life and can be abstract or conceptual. Theme is generally expressed through recurring symbols, motifs, or patterns in a story.

On the other hand, central idea refers specifically to the main point or focus of a non-fiction text, such as an essay or article. It is a concise statement that captures the author's main argument or viewpoint. The central idea provides a clear and specific direction for the reader to follow and understand the author's overall message.

In summary, theme is a broader, more abstract concept found in literature and art, while central idea is a specific and focused point expressed in non-fiction texts.
