What does it mean This is the main body of a piece writing or any various forms in which exists such as book poem an article short story?

The phrase "This is the main body of a piece of writing" refers to the central part of a written work, where the main ideas, arguments, or story are developed and presented.

Here's a breakdown of how it applies to different forms of writing:

* Book: In a book, the main body comprises the chapters that contain the plot, characters, setting, and overall message of the story. It excludes the introductory elements (like the preface or foreword) and the concluding sections (such as the epilogue).

* Poem: The "main body" of a poem is the central section where the poet explores their theme, uses figurative language, and develops the overall mood and rhythm.

* Article: In an article, the main body is the section after the introduction and before the conclusion. It's where the author presents evidence, analysis, and arguments to support their thesis statement.

* Short Story: Similar to a book, the main body of a short story is the central section that unfolds the plot, develops characters, and reveals the story's resolution.

Essentially, the main body is where the "meat" of the writing exists – it's the heart and soul of the piece that delivers the intended message or experience to the reader.
