Understanding the Difference Between Pleonasm and Tautology: What Sets Them Apart?

Pleonasm and tautology are two words that many people have heard of but few fully understand the difference between. Both of these concepts relate to the use of unnecessary or repetitive language, but they differ in important ways. A pleonasm occurs when a writer or speaker uses more words than necessary to convey a message, whereas a tautology is a type of pleonasm in which the same idea is repeated in different words.

To understand the difference between these two concepts, it’s helpful to consider examples of each. A common pleonasm is “ATM machine,” in which the word “machine” is redundant because “ATM” already stands for “automated teller machine.” A tautology, on the other hand, might be something like “true fact” or “unexpected surprise,” in which the same idea is expressed twice in different words. While both of these types of redundancy can be frustrating to readers or listeners, it’s important to recognize that they are not the same thing.

Being able to differentiate between pleonasms and tautologies can help improve your writing and speaking skills. By avoiding these kinds of unnecessary language, you can communicate your message more clearly and succinctly, drawing in your audience and leaving a lasting impression.

Redundancy in Language

Redundancy in language refers to using more words than necessary to convey a message. While redundancy can sometimes be used for emphasis or clarity, it can also lead to pleonasm and tautology.

Both pleonasm and tautology involve using unnecessary words, but there is a subtle difference between the two. Pleonasm is the use of excess words that do not add meaning to a sentence but are not contradictory, while tautology is the use of words that repeat the same idea in slightly different ways.

However, it can be difficult to distinguish between pleonasm and tautology, and they are often used interchangeably. Regardless, both should be avoided in writing as they can make sentences sound clumsy and confusing.

Types of Linguistic Redundancy

One important concept in language is redundancy. This refers to the use of extra words or phrases that are not necessarily needed to convey the intended meaning. Redundancy can be intentional or unintentional. In some cases, it can add emphasis or clarity to a message. In other cases, it can be a sign of poor writing or lack of editing.

  • Pleonasm: This type of redundancy occurs when unnecessary words or phrases are included in a sentence that do not add any extra meaning. For example, “I saw it with my own eyes” is an example of pleonasm because the phrase “with my own eyes” is unnecessary since the only way to see something is with one’s own eyes.
  • Tautology: This type of redundancy occurs when the same idea is repeated using different words. For example, “He is a male man” is an example of tautology since the word “male” and “man” mean the same thing. Another example is the phrase “free gift” since a gift is already assumed to be free.
  • Clichés: Clichés are overused phrases or expressions that have lost their original meaning and impact. Examples include “at the end of the day” and “think outside the box.”

Examples of Linguistic Redundancy

Here are some examples of sentences that contain unnecessary words or phrases:

  • “She nodded her head.”
  • “We climbed up to the top.”
  • “He entered into the room.”

These sentences could be rewritten in a more concise way:

  • “She nodded.”
  • “We climbed to the top.”
  • “He entered the room.”

Pitfalls to Avoid

When writing, it is important to be mindful of redundancy. Here are some pitfalls to avoid:

  • Don’t use unnecessary words or phrases.
  • Avoid repeating the same idea using different words.
  • Avoid using clichés.

By making an effort to reduce redundancy in your writing, you can create clearer and more effective communication.

Type of Redundancy Definition Example
Pleonasm Using unnecessary words or phrases that do not add any extra meaning. “I saw it with my own eyes.”
Tautology Repeating the same idea using different words. “He is a male man.”
Clichés Overused phrases or expressions that have lost their original meaning and impact. “Think outside the box.”

Remember to make every word count in your writing.

Examples of Pleonasm

Pleonasm is a frequently used figure of speech, often used in literature and everyday conversation. It involves the use of redundant words or phrases, sometimes unintentionally, with the aim of emphasizing a particular point. Here are some examples of pleonasm that are commonly used:

  • “Free gift” – The word ‘gift’ already suggests that something is given without charge, making the word ‘free’ redundant.
  • “End result” – The word ‘result’ already implies that something is an end product or outcome, making the word ‘end’ unnecessary.
  • “New innovation” – The word ‘innovation’ means the introduction of a new idea, method, or product, making the word ‘new’ unnecessary.

Pleonasm can also be used to create emphasis in a sentence, for example:

“I saw it with my own eyes” – The use of “with my own eyes” is redundant, but serves to emphasize the fact that the speaker witnessed the event personally.

Examples of Tautology

Tautology is a form of redundancy in which the same meaning is expressed twice but in different words. This type of expression is often used subconsciously. It’s vital for writers to avoid tautology in their writing as it can weaken their message.

  • “New beginner” – Using “new” and “beginner” together is redundant as “beginner” already implies that they are new.
  • “Future plans” – Plans are always intended for the future, so adding “future” is not necessary.
  • “Unexpected surprise” – If it was expected, then it wouldn’t be a surprise. Using both words cancels each other out and weakens the impact of the sentence.

It’s essential to note that tautology can also be seen in idioms and common expressions. For instance, “safe haven” can be considered a tautology since a haven is, by definition, a safe place.

Moreover, tautology can be used in daily conversation, but it’s ill-advised to use it in writing as it can make the text sound redundant and weaken the argument. In the table below, we’ve listed some examples of common tautologies that should be avoided when writing:

Keeping an eye out for tautology in your writing can help you improve your writing style and craft more impactful sentences. Remember to be concise and only use words that add value to your message.

Significance of avoiding redundancy in writing

Good writing is concise and clear. One of the most significant aspects of writing concisely is avoiding redundancy. Redundancy happens when there is a repetition of words or ideas in a sentence, paragraph, or entire document. When redundant phrases or words occur, they add no significant value to the text and can confuse the readers or make them lose interest.

  • Redundancy makes a text longer than necessary. A lengthy text can be challenging and time-consuming to read, resulting in a loss of interest by the readers. A concise text, on the other hand, is more engaging and easier to comprehend.
  • Redundancy can weaken the impact of a sentence or idea. Repetitive words or phrases make the sentence or idea redundant and less impactful. A writer’s goal is to convey their intended message precisely and creatively, which can be achieved by avoiding redundancy.
  • Redundancy can make a writer appear unprofessional. When a writer utilizes redundant words or phrases, they reduce the quality of their writing, making it appear amateurish and poorly written. A professional writer should endeavor to use concise and relevant words to convey their intended message.

Good writing is all about clear and concise communication. A writer who avoids redundancy conveys their intended message effectively. By eliminating redundant phrases or words, a writer makes their text more engaging, informative and provides a better reading experience for the reader.

Difference between pleonasm and tautology

Both pleonasm and tautology are linguistic devices that involve the use of redundant words. However, their specific meanings and usage differ in subtle but important ways.

  • Pleonasm: This is the use of more words than are necessary to convey meaning. It often involves using synonyms or descriptive phrases that add little to the overall message of a sentence.
  • Tautology: This is a particular type of pleonasm that involves using words that repeat the same idea or concept. In other words, a tautology is a statement in which a particular word or phrase is repeated in order to emphasize its meaning.

Here are some examples to help illustrate the difference:

  • A pleonasm: “The green grass” (since grass is typically green, the word “green” adds nothing to the meaning of the sentence)
  • A tautology: “I saw it with my own eyes” (since “saw” already implies that the speaker personally witnessed something, the phrase “with my own eyes” is redundant)

It’s worth noting that while pleonasms can be seen as errors or mistakes, tautologies are often intentional and used for rhetorical effect. In certain contexts, repeating a phrase can help drive home a specific point or idea, or lend emphasis to a statement.

Pleonasm Tautology
“I heard it with my own ears.” “Absolutely certain.”
“The big giant” “Past history”
“Join together” “End result”

Whether intentional or not, it’s generally considered good writing practice to avoid unnecessary repetition and use concise language to convey your message clearly and effectively.

Strategies for minimizing redundancy in writing

Good writers know that redundancy can negatively impact their writing. It can make the content boring and excessive, decrease reader engagement, and lead to confusion. As a writer, you should aim to minimize redundancy in your writing.

Here are some strategies for doing so:

  • Avoid pleonasm and tautology: The first step to minimizing redundancy is to understand the difference between pleonasm and tautology. As discussed earlier, pleonasm refers to the use of unnecessary words that convey the same meaning, while tautology is the use of redundant words or phrases that repeat the same idea. Avoiding these two can help reduce redundancy in your writing.
  • Write concisely: One of the best ways to avoid redundancy is to write concisely. This means using fewer words to convey your ideas clearly. Avoid using excessive words or phrases that do not add value to your content. Edit your work to remove any unnecessary words or phrases.
  • Use active voice: Active voice makes your writing more concise and direct. It also reduces the number of redundant words you use. Passive voice, on the other hand, often leads to wordy and redundant sentences. Whenever possible, use active voice to make your writing more engaging and straightforward.

Additionally, the following strategies can help you minimize redundancy in your writing:

  • Eliminate unnecessary adjectives and adverbs: Adjectives and adverbs can be useful in providing detail and describing things. However, they can also lead to redundancy if overused. Use them sparingly and only when necessary.
  • Vary your sentence structure: Using different sentence structures can help to keep your writing interesting and engaging. If you use the same sentence structure repeatedly, your content can become monotonous and redundant.
  • Use transitional phrases: Transitional phrases help to connect ideas and create a smooth flow of content. By using transitional phrases, you can reduce redundancy by avoiding the repetition of the same idea or concept.


Minimizing redundancy in your writing can help improve the flow of your content and make it more engaging to readers. By avoiding pleonasm and tautology, writing concisely, using active voice, eliminating unnecessary adjectives and adverbs, varying your sentence structure, and using transitional phrases, you can create content that is clear, concise, and easy to understand.
