Plagiarism is the act of using someone else's work, ideas, or expressions without giving them proper credit. This can include copying text from a book, using images from the internet, or even taking someone else's research findings and presenting them as your own. It is considered unethical and can lead to serious consequences in academic and professional settings. To avoid plagiarism, it's important to always cite your sources. This means providing information about where you found the material, such as the author's name, the title of the work, and the publication date. Tools like citation generators can help you format your references correctly, ensuring that you respect the original creators of the content you use.
