Content Etiquette

Etiquette is the set of conventional rules of personal behaviour in polite society, usually in the form of an ethical code that delineates the expected and accepted social behaviors that accord with the conventions and norms observed by a society, a social class, or a social group.

Hence, from the above definitions, I deduced that etiquette has to do with rules and regulations which govern a particular group of people and which binds them together as they achieve their common objectives.

Plagiarism

Plagiarism is the representation of another author's language, thoughts, ideas, or expressions as one's own original work. Plagiarism is considered academic dishonesty and a breach of journalistic ethics. Wikipedia Source

According to the Merriam-Webster online dictionary, to "plagiarize" means:

to steal and pass off (the ideas or words of another) as one's own to use (another's production) without crediting the source to commit literary theft to present as new and original an idea or product derived from an existing source

plagiarism is an act of fraud. It involves both stealing someone else's work and lying about it afterward.

How To Avoid Plagiarism

To Avoid plagiarism is actually easy to do now that you have a foundational understanding of what it is. To help you steer clear of this taboo, here’s how to avoid plagiarism in your writing.

CITIATION

To cite a source, one need to add a link that can lead the users to the source of that particular content and this practice will enable me to achieve a well structured and cited article. If individual definitions are used from a different author, the link should be placed immediately after the text with the appropriate mark down style.

When you’re researching for a blog post, whitepaper, webinar, or other pieces of long-form content, you’ll likely find several sources for the information you’re after.

When one look closely, however, one will likely find that many of those sources, all found that information somewhere else – from a reputable primary source. That’s as long as the sources, one that looks solid, informative ones, not ones intended to be purely entertaining.

Include quotations

If you insert a source’s words into your writing, verbatim, one of the most simple yet obvious ways to avoid plagiarism is by using quotation marks around the text to denote that the words aren’t your own. A direct quote should also cite the source so that readers know who the quote is from.

Paraphrase

Paraphrasing means rewriting a source’s ideas or information into your own words, without changing its meaning.

But be careful—paraphrasing can slip into plagiarism if done incorrectly.

Paraphrasing without plagiarizing involves a bit of a dance. Reword and format your writing in an original way, and try to avoid using too many similar words or phrases from the source. The key is to do so without altering the meaning of the idea itself. Remember, you’re still using another’s idea so you’ll need to include a citation to the source.

Present your own idea

Instead of copying the source’s ideas or words, explore what you have to say about it. Ask yourself what unique perspective or point you can contribute in your writing that’s entirely your own.

Keep in mind that if you’re alluding to a source’s ideas or words to frame your own point, you’ll still need to apply the guidelines above to avoid plagiarizing.
