It seems there might be a slight misunderstanding in your request. The phrase “poper mannel” does not appear to be a standard English term or phrase. If you meant to ask about “proper manner” in writing, I’d be happy to explain that.

When it comes to writing, adhering to a proper manner or style is crucial for effective communication. Here are some guidelines for maintaining a proper manner in writing:

1. Clarity: Ensure your writing is clear and straightforward. Use simple and concise language to convey your message effectively. Avoid ambiguity and convoluted sentences that might confuse the reader.

2. Grammar and Spelling: Use correct grammar, punctuation, and spelling. Errors in these areas can undermine the credibility of your writing and distract the reader from your intended message.

3. Organization: Structure your writing logically. Use paragraphs and headings to break up your content and make it easier to read and understand. Each paragraph should focus on a specific point or idea.

4. Audience: Consider your audience and tailor your writing to suit their level of understanding and interest. Use appropriate tone and language, depending on whether you are writing formally or informally.

5. Avoid Jargon: If writing for a general audience, minimize the use of technical jargon or industry-specific terminology that might be unfamiliar to readers.

6. Consistency: Be consistent in your use of tense, writing style, and formatting throughout the piece. Inconsistencies can make the writing appear unprofessional.

7. Cite Sources: When using information or ideas from other sources, provide proper citations to give credit to the original authors and avoid plagiarism.

8. Edit and Revise: Always review and edit your writing before finalizing it. Look for errors, improve sentence structure, and ensure your writing flows smoothly.

9. Stay on Topic: Stick to the main subject or theme of your writing. Avoid going off on tangents that could confuse or distract the reader.

10. Engage the Reader: Use hooks, compelling examples, or anecdotes to engage the reader and keep them interested in your writing.

Remember that the appropriate manner of writing can vary depending on the context and purpose of your piece. For academic or professional writing, a formal tone is usually preferred, while a more relaxed and conversational style might be suitable for personal or informal writing. Always consider the specific requirements and expectations for the type of writing you are doing.
