Structure:
* Topic Sentence: This is the main idea of the paragraph, usually placed at the beginning.
* Supporting Sentences: These elaborate on the topic sentence, providing evidence, examples, or explanations.
* Concluding Sentence (Optional): This summarizes the main point or transitions to the next paragraph.
Characteristics:
* Unity: All sentences focus on a single idea, directly related to the topic sentence.
* Coherence: Sentences flow smoothly and logically, connecting with transitions and clear pronoun references.
* Development: The paragraph provides enough information to fully explain the main idea.
* Length: There's no strict length requirement, but a paragraph should be long enough to cover the topic comprehensively.
* Formatting: A paragraph is typically indented from the left margin and has a single space between sentences.
Example:
"The internet has revolutionized communication. Email allows instant and convenient messaging, replacing traditional letters and phone calls. Social media platforms connect people globally, enabling real-time interaction and information sharing. Online forums and chat groups foster communities built around shared interests. These tools have transformed the way we interact, learn, and build relationships."
Note: This is just a basic definition. There are many different styles of writing and purposes for paragraphs, so the specific characteristics may vary.
