Tautology is the needless repetition of a word, phrase, or idea. The word, first used in 1566, comes from the ancient Latin and Greek word “tautologia,” meaning the saying of the same thing twice.
Here are some common examples of tautology in everyday language:
PIN means “personal identification number,” so saying “number” again is unnecessary.
GPS means “global positioning system,” so you don’t need to add the word “system.”
By definition, an innovation is new, so using the two words together is needless repetition.
Exaggerate means to overstate; therefore, “over-exaggerate” is redundant.
See if you can spot the tautology in this sentence:
If you said that using both “$” and “dollars” is redundant, you’re correct! Here’s how we can fix this mistake:
Here’s another example:
Using “am” and “morning” together is unnecessary because they indicate the same time of day. Here are two ways to rewrite this sentence:
Let’s look at one more example:
If you said that using both “I” and “personally” is redundant, you’re right! Let’s see how to correct this:
It’s best to avoid tautology in academic writing. Needless repetition will make your writing wordy, and your readers may struggle to identify your main idea.
Here’s an example of tautology in academic writing:
Using “in addition” or “additionally” with “also” is a common mistake. These words and phrases have the same meaning, so they should not be used in the same sentence.
We can correct this sentence in two ways:
Let’s look at the next example:
As in the above example, using “also” and “as well” in the same sentence is redundant because they have the same meaning. This is true for any combination of “too,” “as well,” “also,” “in addition,” and “additionally.”
Here’s how we can fix this mistake:
Here’s another common mistake that can clutter up your academic writing:
If you noticed that the phrase “their own” is redundant, you’re correct. This is also true for “his own” or “her own.” In this case, since the authors’ names are listed, there is no need to use a possessive pronoun to indicate whose deep learning machine it is.

The next example shows a mistake often seen in reflective writing:
“In my opinion” and “I think” have the same meaning. Instead, we can write one of the following:
Here’s one more example of tautology in academic writing:
In this example, there is a signal phrase indicating the tautology: “in other words.” This phrase is difficult to use effectively and generally leads to needless repetition. There is no need to say both “external appearance” and “geographical aspect” here because they have similar meanings.
Let’s fix this statement to remove the tautology:
As a literary device, tautology can be used in writing to emphasize or clarify a point.
Here are some famous examples:
“To be or not to be, that is the question.”– William Shakespeare, Hamlet, Act 3, Scene 1
“To be or not to be, that is the question.”
Here, it’s repetitive to say “that is the question” right after asking the question.
“While I nodded, nearly napping, suddenly there came a tapping, as of someone gently rapping, rapping at my chamber door.”– Edgar Allen Poe, The Raven
“While I nodded, nearly napping, suddenly there came a tapping, as of someone gently rapping, rapping at my chamber door.”
In this example, “tapping” and “gently rapping” have the same meaning, and “rapping” is repeated.
As we’ve just seen, tautology can be used intentionally in writing, but it’s still important to avoid being repetitive or redundant. If you’re struggling with repetition or wordiness in your writing, we’ll proofread your first 500 words for free!
