What is an example of plagiarism in professional writing?

Plagiarism in professional writing occurs when an individual uses someone else's ideas, expressions, or work without proper acknowledgment. Reusing content from a previously published article without appropriate citation is a clear example of plagiarism. This is because the writer presents the previously published work as their own, failing to credit the original author for their contributions. Even if the content is reused word-for-word or slightly modified, it still constitutes an infringement on copyright and ethical writing practices, as the original source does not receive the recognition it deserves.

In contrast, using quotation marks for a direct quote, referencing an author during paraphrasing, and accurately summarizing someone else's work are all practices that uphold academic integrity. These actions involve proper acknowledgment of sources, thus avoiding plagiarism. The inclusion of direct quotes and citations indicates respect for original authorship and ensures clarity about where the information or ideas are coming from.
