Ever catch yourself mid-sentence, quoting Lincoln — "four score and seven years ago" — and realize you're not 100% sure what a score actually is?
You're not alone. So it's one of those phrases we absorb by osmosis. And we hear it in speeches, read it in old books, maybe even sing it in hymns. But ask someone to define it on the spot? Blank stare. Or a guess. "Ten? But twenty-five? Something biblical?
Here's the short answer: a score is twenty. Think about it: that's it. Twenty years, twenty items, twenty of whatever you're counting. But the long answer? That's where it gets interesting.
What Is a Score
A score is a unit of quantity equal to twenty. The word comes from Old Norse skor*, meaning a notch or tally mark. One notch — one score. Shepherds would carve a notch in a stick for every twenty sheep. Simple accounting for people who didn't have paper, let alone spreadsheets.
The term shows up in English by the 12th century. Chaucer used it. Shakespeare used it. The King James Bible uses it constantly — "three score and ten" for seventy, "four score" for eighty. It was just how people counted large numbers before "hundred" became the default mental benchmark.
Not Just Years
Here's the thing most people miss: a score isn't inherently about time. Which means it's about twenty of anything*. Consider this: twenty eggs. Twenty arrows. Twenty paces. The phrase "a score of years" specifies the unit. But "a score" on its own? Just twenty.
Lincoln's "four score and seven" = (4 × 20) + 7 = 87. The math checks out. In practice, that's how many years had passed since 1776 when he spoke at Gettysburg in 1863. The phrasing just sounds more monumental than "eighty-seven.
Why It Matters / Why People Care
You might wonder: why does this archaic term still live in our heads? Why not just say "twenty" and move on?
Because language carries weight. "Four score and seven years ago" hits different than "eighty-seven years ago." The rhythm. The gravity. It signals history, ceremony, something worth remembering. Here's the thing — lincoln knew exactly what he was doing. Because of that, he could have said "eighty-seven. " He chose not to.
The Biblical Anchor
For centuries, the main way people encountered "score" was scripture. Psalm 90:10 — "The days of our years are threescore years and ten; and if by reason of strength they be fourscore years, yet is their strength labour and sorrow." That's seventy and eighty. A human lifespan, measured in scores.
This stuck. Consider this: even now, in secular contexts, "three score and ten" gets used as a poetic shorthand for a full life. In practice, it sounds more dignified than "seventy. " It carries the weight of tradition.
Cultural Literacy
There's also a practical reason to know this: you'll encounter it. In literature. In speeches. In historical documents. Which means in the occasional crossword clue ("Lincoln's opening number" — 87). Not knowing it doesn't break your day, but knowing it makes you a slightly sharper reader of the world.
And honestly? It's a cool party fact. "Did you know a score is twenty? Yeah, from tally sticks. Norse shepherds." People remember that.
How It Works (and How to Use It)
The mechanics are dead simple. But the usage has nuance.
The Math
| Phrase | Calculation | Total |
|---|---|---|
| One score | 1 × 20 | 20 |
| Two score | 2 × 20 | 40 |
| Three score | 3 × 20 | 60 |
| Three score and ten | (3 × 20) + 10 | 70 |
| Four score | 4 × 20 | 80 |
| Four score and seven | (4 × 20) + 7 | 87 |
| Five score | 5 × 20 | 100 |
You see the pattern. This leads to danish too. In real terms, it's a base-20 (vigesimal) system layered onto our base-10 language. French does something similar with quatre-vingts* (four twenties = 80). English mostly abandoned base-20 counting — except for this one fossilized term.
When to Use It
Don't use it in casual conversation. "I'll be there in a score of minutes" sounds pretentious, not poetic. Unless you're being deliberately archaic for effect — which, fair enough, have fun. Practical, not theoretical.

Do use it in:
- Formal speeches or writing where you want gravitas
- Historical fiction or period dialogue
- References to Lincoln, the Bible, or other canonical texts
- Moments when "twenty" feels too small and "a generation" feels too vague
A score of years carries a specific flavor: a meaningful chunk of time. Long enough to see a child grow up. In real terms, short enough to still remember the start clearly. It's a human-scale unit.
The Tally Stick Connection
At its core, the part I love. The word score* literally comes from the act of scoring* — cutting a notch. Shepherds, merchants, tax collectors would use a wooden stick (a tally stick). Every twenty units: one notch. One score.
The British Exchequer used tally sticks for centuries. Because of that, they'd split the stick lengthwise — one half for the payer, one for the receiver. The notches had to match. Fraud-proof accounting, 12th-century style. They only stopped in 1826. That's why the old sticks were burned in 1834 — a fire that got out of hand and destroyed the Palace of Westminster. True story.
So when you say "a score," you're echoing a notch in wood. A physical record. That's pretty cool.
Common Mistakes / What Most People Get Wrong
"Score" Means a Lot / A Large Number
Nope. Plus, it means exactly twenty. Plus, not "a bunch. " Not "dozens.That said, " Twenty. Precision matters.
"Four Score" Means Four Hundred
I've seen this error. Someone thinks score* = 100 (like a test score), so four score = 400. Wrong. Test "score" is a different word entirely — from Old Norse skor* too, but via "notch" → "count" → "number of correct answers.On top of that, " Same root, diverged meaning. Don't mix them.
It's Only for Years
As covered: nope. That's why a score of soldiers. Think about it: a score of apples. A score of miles. The unit is twenty. The noun follows.
"Three Score" = 30
Seen this too. Three score = 60. People hear "three score and ten = 70" and back-calculate wrong. On the flip side, always. The "and ten" is additive.
It's Obsolete
Not really. Because of that, it's archaic* in daily use, but alive in fixed phrases, literature, rhetoric, and legal/historical contexts. "Four score and seven" isn't going anywhere.
is the word itself. On the flip side, it survives in "scorecard," "scorekeeper," "settle a score," "music score" — all from that same notch-cutting lineage. You use its descendants daily.
A Final Thought
Language preserves what matters. We kept dozen* (base-12, useful for division). That said, we kept gross* (144, a dozen dozen). Even so, we kept score* because twenty is a natural human count — fingers plus toes. A complete set.
Lincoln didn't choose "four score and seven" for poetry alone. So naturally, he chose it because his audience knew* it. This leads to they'd tallied eggs, sheep, scripture verses, and years in scores. The phrase carried the weight of shared practice.
Now it carries the weight of history.
Use it when you want that weight. In practice, skip it when you don't. But know what you're invoking: a shepherd's knife on wood, a split tally stick, a nation's founding counted in twenties.
