Why Is A Score 20 Years

Why is a Score 20 Years? Understanding the Origin and Usage of the Term

When we hear the phrase "four score and seven years ago" from Abraham Lincoln’s Gettysburg Address, most people immediately recognize it as a reference to 87 years. On the flip side, for those unfamiliar with the term, the question arises: why is a score 20 years? Understanding the meaning of a "score" requires a journey back into the history of linguistics, mathematics, and the way ancient civilizations tracked quantities before the modern decimal system became the global standard.

Introduction to the Concept of a Score

In modern English, the word score is most commonly associated with sports—the tally of points gained during a game. Still, in an archaic or formal context, a score is a group or set of twenty items. When applied to time, a score represents a period of 20 years.

This system of counting is known as a vigesimal system (base-20), which differs from our current decimal system (base-10). While we typically count in tens and hundreds today, many ancient cultures found the number twenty to be a more natural building block for counting. The transition from using "score" as a primary counting unit to a literary relic reflects the evolution of human mathematics and language.

The Etymology: Where the Word Comes From

To understand why a score equals twenty, we must look at the word's origin. The term "score" derives from the Old Norse word skor, which means a notch, tally, or cut.

Before the invention of paper, pencils, and digital calculators, people needed a physical way to keep track of livestock, trade goods, or time. On top of that, they used a method called tallying. A person would take a piece of wood or a bone and carve a notch (a score) into it for every item counted.

Because counting individual notches one by one became tedious for large numbers, they developed a system of "grouping." Once they reached twenty notches, they would make a deeper, more prominent cut—a major score—to signify that one full set of twenty had been completed. Because of this, "one score" literally referred to the mark made after twenty individual counts.

The Logic of Base-20 (Vigesimal Systems)

You might wonder why twenty was chosen instead of ten, given that humans have ten fingers. The answer lies in the anatomy of the human body. While we have ten fingers, we also have ten toes.

Many early civilizations, including the Mayans and the Aztecs, utilized a base-20 system because it allowed them to count using their entire body (fingers and toes). Even in early European cultures, such as the Celts and the Anglo-Saxons, the vigesimal system was prevalent.

The influence of the base-20 system can still be seen in several languages today:

• French: The word for eighty is quatre-vingts, which literally translates to "four twenties."
• Danish: Some traditional ways of counting in Danish still reflect a base-20 structure.

By using "score" to denote twenty, ancient people could simplify large numbers. As an example, instead of saying "eighty," they could say "four score," which was a more efficient way of visualizing the groups of notches on a tally stick.

The Use of "Score" in Literature and History

The reason the term "score" feels "old-fashioned" today is that it shifted from a common counting tool to a stylistic choice in literature and formal speech.

The Gettysburg Address

The most famous use of the term is undoubtedly Abraham Lincoln's 1863 speech. By saying "Four score and seven years ago," Lincoln was not just being poetic; he was employing a biblical cadence. The King James Bible, translated in the early 17th century, frequently used "score" to describe ages (e.g., "Three score and ten" to describe a human lifespan of 70 years). By using this phrasing, Lincoln gave his speech a sense of solemnity, timelessness, and moral authority.

Poetic Meter and Rhythm

Poets and playwrights often used "score" because it fits a specific rhythmic meter better than the word "twenty." In the structure of an English sentence, "four score" provides a different cadence and weight, evoking a sense of antiquity and grandeur that "eighty" simply cannot convey.

How to Calculate Scores in Modern Contexts

Although we rarely use the term in daily conversation, you may encounter it in historical texts or legal documents. Calculating "scores" is a simple multiplication process:

Number of Scores × 20 = Total Number

Here are a few examples for quick reference:

• One score: $1 \times 20 = 20$ years.
• Two score: $2 \times 20 = 40$ years.
• Three score: $3 \times 20 = 60$ years. On top of that, * Four score: $4 \times 20 = 80$ years. * Four score and seven: $(4 \times 20) + 7 = 87$ years.

FAQ: Common Questions About "Scores"

Is "score" only used for years?

No. While we often discuss it in terms of age or time, a score can refer to any group of twenty. As an example, a farmer in the 18th century might have sold his sheep by the score.

Why don't we use it anymore?

As mathematics became more standardized globally, the decimal system (base-10) became the dominant way of teaching and recording numbers. The decimal system is more compatible with the way we perform complex multiplication and division, making the vigesimal "score" system obsolete for practical use.

Is "score" the same as a "dozen"?

No. A dozen is a group of 12, whereas a score is a group of 20. Both are "non-decimal" grouping units that were common in trade and agriculture.

Conclusion: The Legacy of the Tally Stick

The fact that a score equals 20 years is a linguistic fossil—a remnant of a time when humans interacted with numbers physically. From the notches carved into bones to the toes used for counting, the "score" represents the ingenuity of our ancestors in organizing the world around them.

While we now rely on digital screens and base-10 mathematics, the term persists in our most cherished historical documents and poems. Understanding why a score is 20 years allows us to connect more deeply with the history of language and the evolution of human thought. Next time you encounter the word in a book or a speech, you can visualize those ancient tally marks and appreciate the enduring legacy of the vigesimal system.

The Score in Modern Language and Culture

Even though the practical use of a score has faded, its echo can still be heard in contemporary idioms and artistic expressions. Now, phrases such as “the score of a game” or “to score a goal” have become idiomatic, drawing on the notion of a discrete, countable unit. In music, a “score” refers to the written notation of a composition—an homage to the idea of a complete, organized set that can be read, interpreted, and performed. These modern usages preserve the word’s sense of completeness and structured grouping, even when the number 20 itself is no longer in the foreground.

Literary Allusions

Authors across centuries have sprinkled the term into their prose to evoke a sense of gravitas. Likewise, in contemporary fiction, a character might remark, “It’s been a score of seasons since I last saw her,” using the term to lend a lyrical quality to the narrative. To give you an idea, in Charles Dickens’ Great Expectations, the narrator refers to a “score of years” to underline the passage of time in a Victorian setting. The rhythm and cadence of the phrase often carry more emotional weight than a plain numeric description.

Educational Contexts

In classrooms, teachers sometimes bring the concept of a score into lessons on historical numeration systems or on the evolution of counting practices. By comparing the vigesimal system with the decimal, students gain insight into why certain cultures favored different base systems and how these choices influenced commerce, administration, and even literature. Such lessons highlight that numbers are not merely abstract symbols; they are tools shaped by human culture and necessity.

The Score in the Digital Age

The digital era has largely standardized on binary and decimal systems, yet the idea of grouping remains relevant. Still, in computing, data is often counted in “chunks” of 8, 16, or 32 bits—essentially a modern version of a score. So in networking, a “score” of packets might be used to trigger quality-of-service adjustments. In these contexts, the term “score” survives not because of its historical value but because it conveys the concept of a complete set that can be measured, processed, and acted upon.

Why the Score Still Matters

The persistence of the word “score” in our language and culture underscores a broader truth: the way we count and categorize shapes how we perceive the world. Whether we speak of “two scores of years,” “a score of apples,” or “a score of points,” the underlying idea is the same—grouping items into a coherent, manageable unit. This grouping is essential for planning, storytelling, and even emotional reflection. A score becomes a bridge between the tangible and the abstract, linking our past practices to our present understanding.

Final Thoughts

From the carved notches on ancient bones to the rhythmic cadence of a presidential address, the concept of a score has traveled through time, adapting to new contexts while retaining its core meaning. Which means its journey from a practical counting tool to a poetic device illustrates the fluid relationship between language, culture, and mathematics. Which means though we no longer tally sheep or soldiers in sets of twenty, the term “score” lives on, reminding us of humanity’s enduring quest to bring order to the numbers that govern our lives. When you next encounter the word—whether in a historical document, a poem, or a modern conversation—pause for a moment and consider the rich tapestry of human ingenuity that it represents.
