In most citation styles, including APA, MLA, and Chicago style, you can add variety to your research writing by not always using the same sentence structure to introduce quotations, paraphrases, or pieces of information borrowed from different sources. It is relatively simple to use a wide variety of different expressions to introduce both direct and indirect citations. These expressions, which usually occur in the parts of sentences that come just before quotes and paraphrases, are called signal phrases (or, in some cases,  lead-in phrases ). 

Often, signal phrases can be distinguished by the presence of a verb like "indicate" or "argue" that references what the author is doing in the original source. However, a few select signal phrases contain no verbs (e.g., "According to [author],").

In the examples below, the author being cited is Jane Doe. The examples in the first section are adapted to APA, which recommends past-tense verbs  in signal phrases. For MLA (as well as Chicago style), the same verbs can also be used in the present tense instead of the past tense, as the second section below shows. 

Be sure each signal phrase verb matches your intention for the in-text citation. Read the whole sentence after you finish to ensure that the signal phrase grammatically coheres with any content that follows the quote or paraphrase.

Expressing Disagreement with a Signal Phrase

Of course, some quotes and paraphrases express disagreement or negative opinions. In these cases, be sure that any verbs in the signal phrase match the nature of the quote or paraphrase. See the examples below.

Doe rejected  the claim that nature is more important than nurture.

Doe denied  the claim that nature is more important than nurture.

Doe refutes  the claim that nature is more important than nurture.

Doe disputes  the claim that nature is more important than nurture.

Suggested Ways to Introduce Quotations

When you quote another writer's words, it's best to introduce or contextualize the quote. 

How To Quote In An Essay?

To introduce a quote in an essay , don't forget to include author's last name and page number (MLA) or author, date, and page number (APA) in your citation. Shown below are some possible ways to introduce quotations. The examples use MLA format.

Use A Full Sentence Followed by A Colon To Introduce A Quotation

• The setting emphasizes deception: "Nothing is as it appears" (Smith 1).
• Piercy ends the poem on an ironic note: "To every woman a happy ending" (25).

Begin A Sentence with Your Own Words, Then Complete It with Quoted Words

Note that in the second example below, a slash with a space on either side ( / ) marks a line break in the original poem.

• Hamlet's task is to avenge a "foul and most unnatural murder" (Shakespeare 925).
• The speaker is mystified by her sleeping baby, whose "moth-breath / flickers among the flat pink roses" (Plath 17).

Use An Introductory Phrase Naming The Source, Followed By A Comma to Quote A Critic or Researcher

Note that the first letter after the quotation marks should be upper case. According to MLA guidelines, if you change the case of a letter from the original, you must indicate this with brackets. APA format doesn't require brackets.

• According to Smith, "[W]riting is fun" (215).
• In Smith's words, " . . .
• In Smith's view, " . . .

Use A Descriptive Verb, Followed by A Comma To Introduce A Critic's Words

Avoid using says unless the words were originally spoken aloud, for instance, during an interview.

• Smith states, "This book is terrific" (102).
• Smith remarks, " . . .
• Smith writes, " . . .
• Smith notes, " . . .
• Smith comments, " . . .
• Smith observes, " . . .
• Smith concludes, " . . .
• Smith reports, " . . .
• Smith maintains, " . . .
• Smith adds, " . . .

Don't Follow It with A Comma If Your Lead into The Quotation Ends in That or As

The first letter of the quotation should be lower case.

• Smith points out that "millions of students would like to burn this book" (53).
• Smith emphasizes that " . . .
• Smith interprets the hand washing in MacBeth as "an attempt at absolution" (106).
• Smith describes the novel as "a celebration of human experience" (233).

How to Introduce Quotes in Academic Writing

• 3-minute read
• 17th October 2019

It would be hard to write a good essay  without quoting sources. And as well as using quote marks , this means working quotations into your own writing. But how can you do this? In this post, we provide a few helpful tips on how to introduce quotes (short and long) in academic writing.

Introducing Short Quotations

The easiest way to quote a source is to work a short passage (sometimes just a single word) into your own sentence. For example:

The tomb was one of archaeology’s “most intriguing discoveries” (Andronicus, 1978, p. 55) and has fascinated researchers ever since.

Here, the only requirements placing the quoted text within quotation marks and making sure the quote follows grammatically from the surrounding text.

Quoting After a Colon

If you need to quote a source after a full sentence, introduce it with a colon:

On the basis of Philip II’s estimated date of death, Andronicus (1978) draws a conclusion :  “This, in all probability, must be his tomb” (p. 76).

When using a colon to introduce a quotation, the text before the colon must be a full sentence. The text after the colon, however, can be just a few words.

Quoting After a Comma

Alternatively, you can use a comma to introduce a quote. When doing this, the quoted text should follow from the preceding sentence (usually after a word like “says” or “argues”):

Andronicus (1978) says ,  “The weapons bore witness that the tomb could not have belonged to a commoner” (p. 73).

However, when a quote follows the word “that,” no comma is needed:

Andronicus (1978) says  that “The weapons bore witness that the tomb could not have belonged to a commoner” (p. 73).

Block Quotes

Finally, for longer quotations, use a  block quote . These are also introduced with a colon, but they don’t have to follow a full sentence. Furthermore, quoted text should be indented and the block quote should begin on a new line. For example, we could introduce a block quote as follows:

Andronicus (1978) describes the fresco in the following terms:

The barely visible painting depicts three hunters with spears and five horsemen with dogs pursuing their prey, wild boars and lions. This and three other paintings discovered in the adjacent tomb are among the few extant examples of fourth-century BC Greek frescoes. (p. 72)

This emphasizes how important the discovery was for understanding…

Usually, you’ll only need block quotes for passages with more than 40 words (or four lines). The exact rules depend on the reference system you’re using, though, so be sure to check your style guide. And, when in doubt, you can always submit a document for proofreading . We can help make sure your quotations are fully integrated into the rest of your text.

Quoting and integrating sources into your paper

In any study of a subject, people engage in a “conversation” of sorts, where they read or listen to others’ ideas, consider them with their own viewpoints, and then develop their own stance. It is important in this “conversation” to acknowledge when we use someone else’s words or ideas. If we didn’t come up with it ourselves, we need to tell our readers who did come up with it.

It is important to draw on the work of experts to formulate your own ideas. Quoting and paraphrasing the work of authors engaged in writing about your topic adds expert support to your argument and thesis statement. You are contributing to a scholarly conversation with scholars who are experts on your topic with your writing. This is the difference between a scholarly research paper and any other paper: you must include your own voice in your analysis and ideas alongside scholars or experts.

All your sources must relate to your thesis, or central argument, whether they are in agreement or not. It is a good idea to address all sides of the argument or thesis to make your stance stronger. There are two main ways to incorporate sources into your research paper.

Quoting is when you use the exact words from a source. You will need to put quotation marks around the words that are not your own and cite where they came from. For example:

“It wasn’t really a tune, but from the first note the beast’s eyes began to droop . . . Slowly the dog’s growls ceased – it tottered on its paws and fell to its knees, then it slumped to the ground, fast asleep” (Rowling 275).

Follow these guidelines when opting to cite a passage:

• Choose to quote passages that seem especially well phrased or are unique to the author or subject matter.
• Be selective in your quotations. Avoid over-quoting. You also don’t have to quote an entire passage. Use ellipses (. . .) to indicate omitted words. Check with your professor for their ideal length of quotations – some professors place word limits on how much of a sentence or paragraph you should quote.
• Before or after quoting a passage, include an explanation in which you interpret the significance of the quote for the reader. Avoid “hanging quotes” that have no context or introduction. It is better to err on the side of your reader not understanding your point until you spell it out for them, rather than assume readers will follow your thought process exactly.
• If you are having trouble paraphrasing (putting something into your own words), that may be a sign that you should quote it.
• Shorter quotes are generally incorporated into the flow of a sentence while longer quotes may be set off in “blocks.” Check your citation handbook for quoting guidelines.

Paraphrasing is when you state the ideas from another source in your own words . Even when you use your own words, if the ideas or facts came from another source, you need to cite where they came from. Quotation marks are not used. For example:

With the simple music of the flute, Harry lulled the dog to sleep (Rowling 275).

Follow these guidelines when opting to paraphrase a passage:

• Don’t take a passage and change a word here or there. You must write out the idea in your own words. Simply changing a few words from the original source or restating the information exactly using different words is considered plagiarism .
• Read the passage, reflect upon it, and restate it in a way that is meaningful to you within the context of your paper . You are using this to back up a point you are making, so your paraphrased content should be tailored to that point specifically.
• After reading the passage that you want to paraphrase, look away from it, and imagine explaining the main point to another person.
• After paraphrasing the passage, go back and compare it to the original. Are there any phrases that have come directly from the original source? If so, you should rephrase it or put the original in quotation marks. If you cannot state an idea in your own words, you should use the direct quotation.

A summary is similar to paraphrasing, but used in cases where you are trying to give an overview of many ideas. As in paraphrasing, quotation marks are not used, but a citation is still necessary. For example:

Through a combination of skill and their invisibility cloak, Harry, Ron, and Hermione slipped through Hogwarts to the dog’s room and down through the trapdoor within (Rowling 271-77).

Important guidelines

When integrating a source into your paper, remember to use these three important components:

• Introductory phrase to the source material : mention the author, date, or any other relevant information when introducing a quote or paraphrase.
• Source material : a direct quote, paraphrase, or summary with proper citation.
• Analysis of source material : your response, interpretations, or arguments regarding the source material should introduce or follow it. When incorporating source material into your paper, relate your source and analysis back to your original thesis.

Ideally, papers will contain a good balance of direct quotations, paraphrasing and your own thoughts. Too much reliance on quotations and paraphrasing can make it seem like you are only using the work of others and have no original thoughts on the topic.

Always properly cite an author’s original idea, whether you have directly quoted or paraphrased it. If you have questions about how to cite properly in your chosen citation style, browse these citation guides . You can also review our guide to understanding plagiarism .

Using signal or lead-in phrases is an excellent way to give your reader the necessary context to understand why you think the quotation is important to your discussion: 

A signal phrase usually names the author of the source, gives the publication year in parentheses, and often provides some context. It commonly appears before the source material. To vary your sentence structure, you may decide to interrupt source material with a signal phrase or place the signal phrase after your paraphrase, summary, or direct quotation (A Canadian Writer's Reference (5th ed.), Hacker & Sommers, p. 453)

Example:  Gore (1992) asserted the importance of considering the environmental effects of technological advances and noted that, “the appropriateness of a technology becomes increasingly important as its power grows and its potential for destroying the environment expands” (p. 146).

Verbs in signal phrases

Use active and descriptive verbs in your introduction of a quotation: 

(Source: A Canadian Writer's Reference (5th ed.), Hacker & Sommers, p. 454)

For more information, please visit Verbs for Referring to Sources (University of Toronto). No matter how you choose to incorporate the idea into your text, you want to make it clear that you are referring to someone else’s idea, not claiming it as your own.

Deciding the appropriate  verb tense  usually comes down to using the one that best reflects the time period of the action described in the text.

Present or Past Tense in Signal Phrases

The choice of using present or past tense in signal phrases for paraphrases or quotations largely depends on the discipline in which authors are writing or the style guide they’re following.

• Present tense: Lee (2015) argues that…
• Past tense: Lee (2015) argued that…

According to APA Style, "the past tense is appropriate when expressing an action or a condition that occurred at a specific, definite time in the past, such as when discussing another researcher's work" (American Psychological Association [APA], 2020, p. 118). When expressing "a past action or condition that did not occur at a specific, definite time or to describe an action beginning in the past and continuing to the present", use the present perfect tense (e.g, Lee (2015) has used...).

Using the past tense to refer to other researcher's work reflects that the quotation or paraphrase presents the author’s thinking at the time of writing the text, which happened in the past. The published text may not reflect the author’s current thinking, so putting the signal phrase in present tense makes a claim that can’t be investigated within the source material. If you’re unsure of which tense to use in signal phrases, please check with your instructor, supervisor, or journal editor.

Quotations (as well as paraphrases and summaries) play an essential role in academic writing, from literary analyses to scientific research papers; they are part of a writer’s ever-important evidence, or support, for his or her argument.

But oftentimes, writers aren’t sure how to incorporate quotes and thus shove them into paragraphs without much attention to logic or style.

For better quotations (and better writing), try these tips.

Identify Clearly Where the Borrowed Material Begins

The quotation should include a signal phrase, or introductory statement, which tells the reader whom or what you are citing. The phrase may indicate the author’s name or credentials, the title of the source, and/or helpful background information.

Sample signal phrases

• According to (author/article)
• Author + verb

Some key verbs for signal phrases

• says, writes, accepts, criticizes, describes, disagrees, discusses, explains, identifies, insists, offers, points out, suggests, warns

Two Signal Phrase Examples

• According to scholar Mary Poovey, Shelley’s narrative structure, which allows the creature to speak from a first-person point of view, forces the reader “to identify with [the creature’s] anguish and frustration” (259).
• In an introduction to Frankenstein in 1831, the author Mary Shelley describes even her own creative act with a sense of horror: “The idea so possessed my mind, that a thrill of fear ran through me, and I wished to exchange that ghastly image of my fancy for the realities around” (172).

Create Context for the Material

Don’t just plop in quotes and expect the reader to understand. Explain, expand, or refute the quote. Remember, quotations should be used to support your ideas and points.

Here’s one simple, useful pattern: Introduce quote, give quote, explain quote.

“Introduce, Give, Explain” Example 1

[Introduce] Dorianne Laux’s “Girl in the Doorway” uses many metaphors to evoke a sense of change between the mother and daughter: [Give] “I stand at the dryer, listening/through the thin wall between us, her voice/rising and falling as she describes her new life” (3-5). [Explain] The “thin wall” is literal but also references their communication barrier; “rising and falling” is the sound of the girl’s voice but also a reference to her tumultuous preteen emotions.

“Introduce, Give, Explain” Example 2 (longer block quotation)

[Introduce] After watching the cottagers with pleasure, Frankenstein’s creature has a startling moment of revelation and horror when he sees his own reflection for the first time:

[Give] I had admired the perfect forms of my cottagers — their grace, beauty, and delicate complexions: but how was I terrified, when I viewed myself in a transparent pool! At first I started back, unable to believe that it was indeed I who was reflected in the mirror; and when I became fully convinced that I was in reality the monster that I am, I was filled with the bitterest sensations of despondence and mortification. Alas! I did not yet entirely know the fatal effects of this miserable deformity. (76)

[Explain] This literal moment of reflection is key in the creature’s growing reflection of self: In comparing himself with humans, he sees himself not just as different but as “the monster that I am.”

Additional Advice

Pay attention to proper format and grammar (See VU Writing Studio handout Quotation Basics: Grammar, Punctuation, and Style ), and always, always credit your source in order to avoid plagiarism.

Citation styles (e.g. MLA, APA, or Chicago) vary by discipline. Ask your professor if you are uncertain, and then check style guides for formats. (The above examples use MLA format.)

Integrating Quotations in MLA Style

Integrating Quotations (MLA)

A reader may be able to make sense of a quotation dropped into a piece of writing, but introducing or integrating quotations into the flow of your sentence is the way to use them most effectively—to be sure that your reader knows what you mean. You have three options: 

• Introduce the quotation with a statement that puts it in context. A colon follows a formal statement or independent clause.
• Lynn Quitman Troyka warns us of the particular challenges of using quotations in research papers: “The greatest risk you take when you use quotations is that you will end up with choppy, incoherent sentences” (184). 
• Use a signal phrase followed by a comma or a signal verb followed by that to announce a quotation.
• According to Lynn Quitman Troyka, “. . ..”
• The narrator suggests that “. . ..”
• As Jake Barnes says, “. . . . . ..”
• Frye rejects this notion when he argues, “. . ..”
• Integrate the quotation fully into your sentence. The quotation and your words must add up to a complete sentence.
• We know the boy has learned a painful lesson when he says that his eyes “burned with anguish and anger” (Joyce 481). 
• Leaders are inspirational; they are concerned with “providing meaning or purpose in work for employees and creating meaning in the product for customers” (Ivancevich, Lorenzi, and Skinner 341).  
• Researchers found that firms with a strong corporate culture “based on a foundation of shared values” outperformed the other firms by a large margin (Quigley 42).

Quotations within Quotations:

Use single quotation marks to enclose a quotation within a quotation.

• Miller states, “Religions are examples of ‘noble lies’ aimed at uplifting human stature” (18).

Adding Material within Quotations:

Use square brackets to enclose material that you add to or change within a quotation to allow it to fit grammatically into a sentence. 

• Balko (2015) argues, “If they [policymakers] want to fight obesity, they’ll halt the creeping 

socialization of medicine” (p. 142).

• “Today, the [saturated fat] warnings remain a cornerstone of the government’s dietary guidelines,” O’Connor (2016) states, “though in recent years the American Heart Association has also begun to warn that too much added sugar may increase cardiovascular disease risk” (p.92). 

Block Quotations:

Indent longer quotations (more than four lines) ten spaces from the margin. Notice that quotation marks are not used to enclose material that is set off from the text and that the parenthetical reference is placed after the punctuation following the quotation. 

A socially responsible vision can make an organization more attractive to customers, potential employees, and investors.  As consultant Robert Rosen puts it,  

The best companies are values-based and performance-driven.  Their community involvement supports the mission of the business.  Modern employees want to work for companies who make a difference, their customers want to do business with them because they have solid reputations as good corporate citizens, and shareholders enjoy the value such companies represent over the long term. (9)

Shortening Quotations:

Use an ellipsis of three dots to shorten longer quotations by removing non-essential words and ideas from the middle of the quote.  The quotation must fit grammatically into the sentence even with the ellipsis.   It must also retain enough of the quotation so that it still makes sense in your essay and you do not distort its meaning.   You do not need to provide ellipses at the beginning or the end of the quoted material. 

Foer states, “My grandmother survived World War II barefoot, scavenging Eastern Europe for other people’s inedibles . . . So she never cared if I colored outside the lines, as long as I cut coupons along the dashes” (159). 

Complete quote: “My grandmother survived World War II barefoot, scavenging Eastern Europe for other people’s inedibles: rotting potatoes, discarded scraps of meat, skins and the bits that clung to bones and pits. So she never cared if I colored outside the lines, as long as I cut coupons along the dashes.”
