There is no better way to describe plagiarism as plain, common theft and fraud.
“Theft of what?”
To put it plain and simple as possible; Plagiarism is when you steal someone else’s work and claim for it to be your own. It can be ideas, writing, or any form of use of printed or published language use without giving credit to the original source.
This might be a very expansive explanation, yet, the bottom line of it all is very simple to understand. You only need to ask yourself one question: “How much of this work is my own”? If it is not your own work, well, then you stole it from someone and that is plagiarism.
“How can it be fraud?”
This clarifies the theft part, but what about the accusation of fraud? When you submit a plagiarized piece of work to a client you are actually placing him under the impression that it is your work! Work of which you are the original creator and on payment you are transferring the copyright to your client!
It is scandalous to see how many articles written for the web or content pages are duplicated content with only a few synonym changes or scrambling of words to get it Copyscape passed! Just before you smile when you get that confirmation message that no matches have been found for the text you pasted on Copyscape or any other plagiarism checker for that matter, just thing for a moment, you are gambling with your integrity and reputation as a writer here.
• Cutting and Pasting – Wether it is only a couple of words, paragraph, or believe it or not, a whole article and present it as your own work, you are committing plagiarism.
• Making use of others’ headings or titles – If you write an article on fruit and use the title “5 Most Healthy Fruit to Eat” and list 5 types of fruit and I go and write an article using your listed content with the same title it is regarded as plagiarism as well. Scrambling the content will not change anything. However if I list five different kinds of fruit than those you have mentioned in your article, it is not plagiarism.

When one look at the two reasons for plagiarism given above, it becomes clear that those methods are used by lousy and lazy writers. The type of writers we need to get rid of and discard from the industry.
