Tautology (language)

Tautology (language) is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Tautology (language) rather than just read about it. In short: In literary criticism and rhetoric, a tautology is a statement that repeats an idea using near-synonymous morphemes, words or phrases, effectively "saying the same thing twice". Tautology and pleonasm are not consistently differentiated in literature.

Key takeaways

  • Tautology (language) belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Tautology (language) to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Tautology (language) from memory before moving on to harder problems.

Reference excerpt

In literary criticism and rhetoric, a tautology is a statement that repeats an idea using near-synonymous morphemes, words or phrases, effectively "saying the same thing twice". Tautology and pleonasm are not consistently differentiated in literature. Like pleonasm, tautology is often considered a fault of style when unintentional. Intentional repetition may emphasize a thought or help the listener or reader understand a point. Sometimes logical tautologies like "Boys will be boys" are conflated with language tautologies, but a language tautology is not inherently true, while a logical tautology always is.

Etymology

The word was coined in Koine Greek from ταὐτός ('the same') plus λόγος ('word' or 'idea'), and transmitted through 3rd-century Latin tautologia and French tautologie. It first appeared in English in the 16th century. The use of the term logical tautology was introduced in English by Wittgenstein in 1919, perhaps following Auguste Comte's usage in 1835.

Examples

"Convicted felon", a common English phrase. All felons are convicted by the definition of felon. "Only time will tell if we stand the test of time", from the Van Halen song "Why Can't This Be Love" "After we change the game it won't remain the same." from the Blackalicious song "Blazing Arrow" "That tautological statement has repeated an idea." "There once was a fellow from PerthWho was born on the day of his birth.He got married, they sayOn his wife's wedding day,And died when he quitted the earth." Torpenhow Hill, which is claimed to mean "Hill-hill-hill Hill" "...A forget-me-not, to remind me to remember not to forget." from the Benny Hill song "My Garden of Love" "Assless chaps" – chaps by definition are separate leg-coverings; a similar garment joined at the seat would instead be called a pair of trousers. "...und wenn sie nicht gestorben sind, dann leben sie noch heute" (and if they have not died, then they are still alive today), traditional German formula to end a fairy tale (like "they lived happily ever after"). "Former alumni" – alumni means those who are former members of an institution, group, school etc. "Wandering planet" – the word planet comes from the Greek word 'πλανήτης (planḗtēs), which itself means "wanderer". "If you know, you know", a common English phrase. "A pair of two"; by its nature, a pair is two items, so "a pair of two" is redundant. "What's for you won't go by you", a Scottish proverb that is tautological "Örökrangadó derby", the name of a football match contested between MTK Budapest and Ferencváros in Hungary. The name literally translates as "Derby Derby" in Hungarian. "Overexaggerate." An exaggeration is an overstatement, so the over is implied. To "overexaggerate" something means to "over-overstate" it. "Illegal trafficking", a common description of human trafficking, which is already a violation of several local and national laws as well as international law. "Illegal annexation" - under international law, claiming another country's land as your own is an illegal act (e.g. the common Western phrase "Crimea was illegally annexed by Russia in 2014"). "People die if they are killed", an infamous out-of-context quote from the 2006 Fate/stay night anime. “Hot water heater” is a common tautology that is mistakenly used to refer to a water heater, which would become unnecessary if the water was already hot.

Discussion Intentional repetition of meaning intends to amplify or emphasize a particular, usually significant fact about what is being discussed. For example, a gift is, by definition, free of charge; using the phrase "free gift" might emphasize that there are no hidden conditions or fine print (such as the expectation of money or reciprocation) or that the gift is being given by volition. This is related to the rhetorical device of hendiadys, where one concept is expressed through the use of two descriptive words or phrases: for example, using "goblets and gold" to mean wealth, or "this day and age" to refer to the present time. Superficially, these expressions may seem tautological, but they are stylistically sound because the repeated meaning is just a way to emphasize the same idea. The use of tautologies, however, is usually unintentional. For example, the phrases "mental telepathy", "planned conspiracies", and "small dwarfs" imply that there are such things as physical telepathy, spontaneous conspiracies, and giant dwarfs, which are oxymorons. Parallelism is not tautology, but rather a particular stylistic device. Much Old Testament poetry is based on parallelism: the same thing said twice, but in slightly different ways. (Fowler describes this as pleonasm.) However, modern biblical study emphasizes that there are subtle distinctions and developments between the two lines, such that they are usually not truly the "same thing". Parallelism can be found wherever there is poetry in the Bible: Psalms, the Books of the Prophets, and in other areas as well.

Worked examples

Example 1 — a first encounter with Tautology (language)

Start with the simplest possible case. Write down what Tautology (language) claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Tautology (language) before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Tautology (language) ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Tautology (language)

In research
Tautology (language) appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Tautology (language) in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Tautology (language) is common in secondary-school and first-year university syllabi. It links to neighbouring topics Linguistics, Propositions, Rhetoric, so understanding it makes those chapters shorter.
In everyday life
Look for Tautology (language) outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
