What Are Different Types of Plagiarism and How to Avoid Them?

Plagiarism stands as a significant hurdle in achieving academic excellence. It is an act of intellectual theft that goes beyond the basic definition of copy-paste.

Plagiarism involves many intricate layers that delve into the intent, extent, and diverse formats of the plagiarized content. From neglecting to attribute someone’s quotes to recycling one’s previous work, it all falls under the umbrella of plagiarism.

The repercussions of plagiarism depend upon the degree and intent behind the act of using someone’s work without giving a proper credit. Engaging in plagiarism, whether knowingly or unknowingly, not only carries ethical implications but also jeopardizes one’s dignity, in both academic and professional settings.

Hence, it is imperative to understand the different types of plagiarism to prevent even unintentional involvement in such practices.

Most Common Types of Plagiarism

To develop a conscientious approach toward research writing and avoiding plagiarism, it is crucial to have a comprehensive understanding of its different forms. Some of the most common types of plagiarism include:

  1. Complete Plagiarism

This form of plagiarism is widely recognized and prevalent. It involves presentation of the entire body of another person’s work (such as a research article, manuscript, or image) as your own. In this case, the plagiarized version mirrors the original work entirely, with no alterations made, and does not offer credit to where its due.


When a student downloads a research paper from the internet and presents it as their own, falsely claiming an authorship.

  1. Self-Plagiarism

This form of plagiarism occurs when an individual duplicates their own work by reusing their previous content, ideas, phrases, or even data, without a proper citation. It is more concerned with the intent of depicting the content unreported and new, when, in reality, it is not. The deceptive nature of this act leads to self-plagiarism. It is most commonly observed in research journals, damaging the writer’s credibility. Many publishers are now employing plagiarism detection software or tools to curb this form of intellectual theft.


A student submits a new paper on environmental science, reusing paragraphs from their previous work on climate change without citing or acknowledging that it is a recycled portion of their own writing. This would be considered self-plagiarism, as the student presents their own work as if it were new and original in a different academic context.

  1. Direct Plagiarism

Direct plagiarism, also referred to as verbatim plagiarism, involves mirroring of the another author’s words without providing appropriate attributions. When quoting another work in your research, it is essential to use quotations marks or indentation. This should be followed by accurate acknowledgement of the sources cited. It slightly differs from complete plagiarism because it involves copying specific sections of others’ work rather than the entire content. Practicing this tactic to evade academic integrity may result in disciplinary actions against you.

While addressing a research problem, an author might consult secondary sources but only attribute the information to the primary source, neglecting to credit the secondary source.

  1. Mosaic Plagiarism

Mosaic plagiarism, or patchwork plagiarism, involves integrating phrases or text from various sources into one’s own work. Here, the writer copies phrases, passages, and ideas from various sources to create a new text. Despite its complexity, plagiarism checker software can effectively detect it. It requires more effort that simply copying. Therefore, whether intentional or not, it is considered academically dishonest and punishable, even if the source is footnoted.
