Spot Writing Mistakes

Unintentionally plagiarizing isn’t the only thing to worry about—you also don’t want to lose points for small grammatical mistakes. That’s just annoying! Luckily, BibMe Plus will do a spelling check and review your paper for style, punctuation, sentence structure, verb tense, pronoun antecedent agreement, and more! Once you upload a paper, the grammar check scans the text and highlights each grammar issue within your paper. This way, you can clearly see what may be an issue and its context in the paper. Some highlights will include a detailed explanation as to why the issue was flagged. Others will also have an example of how you can fix the issue. That way, you can make an educated decision about what to do next.

Like you saw with our unintentional plagiarism checker, you can review each highlighted area individually and will always be given the choice to either accept or ignore the grammar and spell checker suggestions. BibMe Plus is here to help, but you are always in the driver’s seat and make the final decisions. No changes will be made without your approval.

This service is designed for all writers, from those who have complete confidence in their writing ability to those who are just starting to write.

The grammar check tool is thorough and useful, and it provides as much information as it can to help you write the best paper possible!

The Importance of Citations

Although most teachers mention or require citations for papers and projects, it’s not always clear why they are so important. We cite our sources for a few important reasons:

  • One, it builds your credibility. Citations show where your information comes from and demonstrates that you are a responsible researcher.

  • Two, citations allow readers to find your sources for themselves. This can contribute to their scholarly advancement as well as vouch for the validity of your own ideas.

  • Finally, and most importantly, it is ethical to do so. Leaving out citations or not indicating where you found an idea means you are taking credit for someone else’s work. That’s not ethically right and could be considered plagiarizing. We always want to be honest in our writing and cite our sources.

To summarize, citing helps us produce essays that obey the guidelines of responsible and ethical research papers. It doesn’t matter whether you are using APA format, MLA format, or more styles. The bottom line is that citations add credibility, enable readers to become authorities on your topic for themselves, and maintain honesty. Citing, therefore, is beneficial for everyone involved in an essay.

What is Plagiarism & Definitions

You may be wondering, just what is plagiarism? How do you define plagiarism? When does it happen? How should I work to try to avoid it in the first place? These are incredibly important questions when attempting to write a paper ethically and responsibly. To answer them, let’s begin with a plagiarism definition so we can understand why citing our sources is key.

A quick and easy plagiarism definition is that it’s the use of someone else’s work or ideas without proper attribution or citation. Sometimes, writers knowingly plagiarize. However, many instances are unintentional. Whether it is intentional or not, there are usually consequences to deal with. These consequences can include a failed grade or course, disciplinary action, a complete repeat of the entire assignment, and even expulsion (eek). Being accused of plagiarism is never a fun matter. So, now that you know what is plagiarism, acknowledge the use of other authors’ work and ideas in your projects. You’ll feel good about your contribution to new knowledge in the world and you’ll be able to submit your assignments more confidently.

Examples of Plagiarism

Now that you have a solid plagiarism definition in your brain, let’s check out the tricky ways it can show its scary face in our papers.

Direct Plagiarism:

What do screened calls, theft, and weight training have in common? They all stem from deliberate actions. Direct plagiarism is the result of deliberately adding another individual’s work or idea into an assignment without providing any type of acknowledgement. Need an example? Copying and pasting direct text from one source into your project, without using quotation marks, or any type of attribution.

Even copying bits and pieces from a sentence, and adding it into a project is a no-no. This is called incremental plagiarism. Whether you’re copying and pasting full sentences, or even just parts, this type is unethical, irresponsible, and just plain dishonest. Moral of the story? Don’t do it.

Thankfully, the BibMe Plus writing tool can help spot instances of this type in papers. If you include text from the Internet in your assignment and accidentally forget to include a reference, BibMe Plus will help you out! The BibMe Plus writing tool will highlight phrases, sentences, or paragraphs in your paper that are found elsewhere on the Internet. Each highlighted section has a prompt that will also ask you if you need a reference for it and will even guide you through the steps of creating that reference. Pretty awesome, right? We think so too.


Patchwriting is pretty similar to patching up a rip in your jeans or a cut on your hand. Even though you might do a good job covering or patching it up, it’s still pretty easy for others to tell something is amiss and there’s a rip or cut underneath. Patchwriting happens when a writer tries to rephrase another author’s words, but the original wording peeks through and is easy to spot. How does it happen? It’s generally the result of a poor attempt at paraphrasing. Perhaps the writer rearranged words in the sentence, subbed out a few words with synonyms, or used bits and pieces of the original wording and mixed it with their own.

Even though this is a form of theft, it’s very different from our first example above. Direct plagiarism is often deliberate and intentional, but patchwriting is often unintentional.

Let’s face it, paraphrasing can be difficult! Especially when authors use tricky vocabulary words in their sentences. Trying to make sense of another author’s jargon-heavy text and spinning it into your own summary can be daunting. We have one piece of advice for you: Understand what it is you’re trying to paraphrase. Otherwise, you’re going to have a really difficult time. Imagine what would happen if your teacher told you about an upcoming project and it was your job to share it with a friend who missed class. Now, imagine how difficult that task would be if you didn’t fully understand the words your teacher used or the meaning of them. Would you be able to share the details of the project with your absent classmate? Probably not. Understanding an author’s words or ideas is crucial to being able to paraphrase properly. So the next time you need to paraphrase, take some time to completely understand what the author is saying.

Worried you may have accidentally plagiarized? The BibMe Plus writing tool has you covered! The plagiarism tool is designed to spot those pesky places in your paper that may get red marks from your teacher. Use the plagiarism check as you’re writing or when you’re through. It will help display areas of concern, highlight suggestions for improvement, and provide grammar suggestions. Simply put, the BibMe Plus essay checker and grammar checker is your go-to for your writing and researching needs.


Plagiarizing another author’s words or idea is one thing, but your own words? Woah. Seems crazy, we know, but it’s real and it happens. Quite often, in fact. What exactly is it? It happens when a previously submitted assignment is reused or refurbished. Yes, we understand you’re using your own words, but it’s still not allowed. Reusing full assignments is completely out of the question, but even reusing portions or paragraphs from former papers is a no-no as well.

Lots of teachers and professors frown upon repurposing old assignments. They want new material that’s fresh. They want to see what you’re capable of doing now, not something you wrote a year or two ago. Prior to digging up an old assignment in your drive, check with your teacher to get the green light. You never know, they might be intrigued by a new spin on a previously written paper. Make sure you cite your own words as well, or at least include a memo sharing that some of the work appeared elsewhere.

What Is Not Plagiarism

Don’t freak out just yet. Not everything is plagiarism. Sit back, relax, and check out these times when you can write your heart out, worry free:

Common Knowledge:

Common knowledge is information that everyone knows. It’s factual information and widely known. Some examples? The Harry Potter series was written by J.K. Rowling, and Paris is the capital of France. These are facts that everyone agrees on and cannot dispute since they’re so widely known. The good news? Common knowledge statements do not need to be cited in a paper. Use them as you please, whenever you want, however you want. Keep in mind though, that research papers showcase new ideas and analysis. Common knowledge is a-okay to add, but make sure you mix in information from outside sources as well.

Attributed Quote or Idea:

With all this talk about intentionally and unintentionally stealing another’s ideas or words, you may be tempted to write a whole paper based only on your own thoughts. However, a solid research paper uses the work of others to build a strong case. Of course it’s ok to talk about someone else’s work as long as you properly attribute any quotes or ideas to them. That’s what references were made for. If you keep reading, we talk about when and how to cite in more detail.

Don’t forget, the BibMe Plus writing tool is a lifesaver when it comes to properly attributing quotes or ideas. It not only suggest where references should be placed in your paper, but it will walk you through how to do it. Talk about a game changer! With just a few pieces of information about the source, such as the title of the source or the author’s name, the BibMe Plus writing tool can help you do the work. That includes help structuring those references exactly as they’re supposed to be structured and developing your references in the style of your choice. Proper style, proper structure, and proper placement equals worry-free papers.

Proper Paraphrase:

As you read above, patchwriting is big no-no, but don’t let this sway you from using another’s idea! A proper paraphrase with a citation is an excellent way to support a point in your paper, while also demonstrating that you fully understand the author’s idea.

Writers sometimes forget to include references when adding paraphrases into papers. It’s easier for writers to remember to add references for direct quotes, but paraphrases sometimes get the short end of the stick. Thankfully, the BibMe Plus writing tool helps you develop accurate references in all types of situations. Quotes, paraphrases, full references, you name it. We do it...and we do it well.

Now that we’ve learned what is and isn’t plagiarizing, let’s look at how to avoid it entirely.

How to Avoid It

With so much information out there, it can be intimidating to think about all the information you have to cite or may accidentally miss citations for. That’s where the BibMe Plus writing tool comes in. It will help you look for and point out spots where you may have similar text to a source on the Internet and ask if you need to create a citation. If yes, there are features to guide you through the process of creating your citation. You can also proactively add in-text citations on your own. Where do they go? Simply put, in-text citations belong after a quote, a paraphrase, or a summary.

Quotes are a no-brainer for needing a citation since you are using an individual’s words verbatim. For paraphrases and summaries, the writing is in your own words, so you may not think a citation is needed. However, since you are restating ideas that are someone else’s, an in-text citation should be added at the end of the last sentence. The citations for all three—quoting, paraphrasing, and summarizing—are in the same format, depending on the formatting style of the entire paper. The BibMe Plus citation generator can help you build these citations and, as a result, build a paper to be proud of that is ethical and has properly formatted citations.

How Citations Help

Plagiarism happens in a variety of scenarios, but the most common ways occur when using excerpts from someone else’s work without quoting them, sourcing information in your research or argument without attribution, and paraphrasing a source without giving the original source credit. To conquer the big scary plagiarism monster, make sure you include citations, also called references, in your paper. References are just as important as your actual research and writing, so take the time to not only include them, but also include them properly.

References have a lot of purposes. They are included to make the reader aware that a piece of information was found elsewhere. They also show the reader that outside sources were used to backup your ideas. Additionally, they provide the reader with an idea of who created that borrowed information or idea.

Whether you’re using a book, magazine, newspaper, journal article, or even a tweet, video, or speech—if you’re adding information into your project from an outside source, reference it. When you’re unsure, it’s better to cite a source than not to. That’s the best advice for preventing plagiarism in your own work.

While we have your attention, don’t forget about the BibMe Plus writing tool. Not only can you check plagiarism with our innovative plagiarism detector, you can also check for grammar. Misspellings, improper word order, subject-verb agreement, and missing punctuation are just a few of the items it will check up on. It will also highlight and flag any issues found, as well as provide suggestions for improvement. As always, BibMe Plus has your back.

When to Add a Citation

Anytime you add a quote, paraphrase, or summarize information from a book, website, or any other source type, include a reference. With so many rules to follow when it comes to structuring these references, it can be tricky to know when, how, and where to place them. That’s where the beauty of BibMe Plus comes in. The BibMe Plus writing tool adds references for you. Yes, you read that correctly. We’ll say it again in case you missed it the first time. The BibMe Plus writing tool adds references for you. Our innovative technology runs a spot check for any quotes or paraphrases in your paper that may be in need of a reference.

How does this work? First things first, we’ll scan your paper and then scan the Internet. What are we looking for? Websites with wording that matches the wording in your paper. If we find any matches, we’ll ask you a simple question, “Do you need to cite this?” If so, we’ll guide you through the steps of adding that reference exactly where it needs to be. We’ll show you a list of websites with content that matches the content in your paper. You might find a few websites listed. Click on the website where you found your information to make sure it’s a match. The tool will take you to a simple form to fill out and do its best to automatically fill out the form for you. If there are any missing fields, you may need to go back to the website (luckily, we include the link for you!) to find the missing information. It may be as simple as finding the author’s name or the date the source was published. After filling out the form to the best of your ability, our plagiarism checker will then structure and place your reference exactly where it needs to be. The best part? We’ll place your reference in the body of your project and also in your bibliography or works cited list. Done and done!

The Different Types of Citations

Now that you understand what citations are, how these nifty little guys help us out, and when to add them, let’s discuss how citations are styled.

  • Parenthetical Citations:

    • They’re only used in the body of a paper, specifically after a quote or paraphrase. To create this type of reference, place parentheses after a quote or paraphrase. Inside the parentheses, include the last name of the author. Depending on the citation style you’re requested to use, there may be other information you need to include as well.

    • Even though these types of references hangout only in the body of the paper, you’re not done yet. Include a full reference at the end of the assignment.

  • In-text Citations:

    • In-text citations have the author’s name in the sentence in parentheses, rather than at the end of the paper. You may need to include the page number or year the source was published in the parentheses at the end. Check out the rules for the specific style you’re using.

    • Just like parenthetical citations, these references also need a full reference at the end of the paper.

  • Footnotes:

    • Footnotes are found in the body of projects. With footnotes, the source information isn’t included in the main part of the writer’s work. The source information is found below, at the bottom of the page.

    • Some styles only need reference information in the footer, and then you’re done. Others require an additional full reference at the end of the assignment. Feeling stuck? Ask your librarian for help!

  • Bibliography:

    • In a nutshell, a bibliography, or reference list, is a list of all the sources used in a project. The bibliography is usually the very last page of a research paper. It lists all of the full citations for the parenthetical, in-text, and footnote citations.

    • Use BibMe.org to create your bibliography. Our fabulous and user-friendly tools walk you through the steps to creating these references.

Quoting, Paraphrasing, and Summarizing

Now that you are familiar with when and where to place a citation, let’s talk about determining how you use a source. Specifically, how do you know whether you are using a quote, paraphrase, or summary?

This might sound tricky, but it’s actually not very difficult to tell the difference between a quote and a paraphrase or summary. Quotes are clearly marked with quotation marks because they are word-for-word repetitions of a source. When you copy and paste from a website, for example, the sentence or passage should be placed within quotations marks at the beginning and end of the words. Of course, a citation is needed for any quotes.

With a paraphrase, you are taking a specific passage, such as a series of paragraphs, and rewriting it in your own words. Paraphrasing is useful for condensing a lot of information into a smaller amount of space. Because a paraphrase is technically your own words, you do not use quotation marks. However, a citation is still needed because the ideas are not your own.

With a summary, you are taking the main ideas of an entire source and writing about them in a few sentences (or more). Like paraphrasing, summaries are in your own words, so they do not need quotation marks. Also like paraphrasing, summaries are not your original idea, so they will need a citation.

Remember that when in doubt, cite—especially after a quote, paraphrase, or summary. Don’t worry, though, the BibMe Plus writing tool is here to help! It can scan your paper for problematic text and missing citations as well as help you properly cite your sources.

Why Is Grammar Important?

Correct grammar is the foundation of any written piece. You cannot successfully communicate your thoughts and points without it. For example, an adverb or interjection could lose its impact if incorrectly placed, inconsistent tenses in a sentence can cause confusion, and a paper without a single preposition would sound very odd. Without grammar, nothing you write would make sense to anyone else.

In addition, your paper must have proper grammar to be taken seriously. Can you imagine a paper with misspelled words, a missing determiner, bad punctuation, misused adjectives, wrong verb tenses, inaccurate noun capitalization, and odd sentences getting an A+? We think not. We’ll conduct a spell check and look for incorrectly used words, verbs that don’t match subjects, misplaced commas or semicolons, an incorrect conjunction, redundancy in sentence structure, and punctuation. But it goes into even more depth as well, checking for words that interrupt the flow of your writing, which is useful for optimizing readability. You may enjoy further reading about strategies regarding grammar feedback.

This service helps writers avoid accidental or unintentional plagiarism, an element that builds credibility, maintains ethical writing, and points readers to places where they can start their own research. Let the BibMe Plus writing tool help you improve your next paper and learn to write and cite smartly and strategically!
