13 Fascinating Facts About the Oxford English Dictionary

The Oxford English Dictionary calls itself “the definitive record of the English language, featuring 600,000 words, 3 million quotations, and over 1000 years of English.” As the English language continues to evolve, the dictionary has flourished and regularly added new words—in 2023 it added more than 700, including air fryer (“a small convection oven, typically used to fry foods using very little oil”), parasocial (“designating a relationship characterized by the one-sided, unreciprocated sense of intimacy felt ... for a well-known or prominent figure”), and superyacht (“an exceptionally large or powerful yacht”). Get to know it better.

1. The Oxford English Dictionary (OED) was built on volunteer labor.

When the London Philological Society came up with the idea for a new dictionary of the English language in 1857, the editors decided it was necessary to enlist the help of the public and asked avid readers to send examples of sentences that could illuminate the meanings of different words. Every day, volunteers mailed thousands of “quotation slips” from books, newspapers, and magazines. By the time the first edition was published, more than 2000 volunteers had assisted the editors in its completion.

2. It took more than 70 years to complete the first edition of the OED.

Originally, the Philological Society predicted that the dictionary would take about 10 years to complete. Twenty-seven years later, the editors had successfully reached the word ant. Knowing it would be a while until a completed book was ready, they began publishing unbound editions of the work-in-progress in 1884. The first full volume was eventually published in 1928, more than 70 years after the society first came up with the idea.

3. The OED started out messy. Very messy.

Frederick Furnivall, one of the dictionary’s founders, was a visionary—but that vision did not extend to his organizational skills. Under his stewardship as editor, the dictionary was a mess. Quotation slips were stuffed haphazardly into bags and went missing. All of the words starting with pa went AWOL for 12 years and were eventually discovered in Ireland. Slips for the letter g were nearly burned with somebody’s trash. All of the entries for the letter h somehow turned up in Italy.

4. OED co-founder Frederick Furnivall was a controversial figure.

After founding a controversy-riddled Shakespeare Society, Furnivall fell into a six-year feud with the poet Algernon Charles Swinburne. Swinburne (whose mastery of the English language earned him six nominations for the Nobel Prize in Literature) mocked Furnivall’s club by calling it “Fartiwell and Co.” and “The Sh*tspeare Society.” Furnivall reached into his bag o' insults and said that Swinburne had, “the ear of a poetaster, hairy, thick and dull.”

5. Dr. James Murray helped the OED clean up its act.

Dr. James Murray, a philologist, took the helm as the dictionary’s principal editor in 1879 and remained in that position for the rest of his life (he died in 1915). Murray was a linguistic superstar; he was proficient in Italian, French, Catalan, Spanish, Latin, Dutch, German, Flemish, and Danish and also had a solid grasp of Portuguese, Vaudois, Provençal, Celtic, Slavonic, Russian, Persian, Achaemenid Cuneiform, Sanskrit, Hebrew, Syriac, Aramaic Arabic, Coptic, and Phoenician.

6. Murray built a shed for the OED's editors to work in.

In 1885, to better organize the dictionary, Murray constructed a sunken shed made of corrugated iron to house the editors and their precious quotation slips. Called the “Scriptorium,” this linguistic workshop contained 1029 pigeonholes that allowed Murray and his subeditors to arrange, sort, and file more than 1000 quotation slips each day. 

6. Only one word is known to have gone missing.

Only one quotation slip—containing the word bondmaid—is known to have been lost. (It fell down behind some books and the editors never noticed.) Murray was deeply embarrassed by his failure to include the word in the dictionary. “ot one of the 30 people (at least) who saw the work at various stages between MS. and electrotyped pages noticed the omission,” he said. “The phenomenon is absolutely inexplicable.” The word was officially introduced in a 1933 supplement.

7. One of the OED’s most prolific contributors was a murderer confined to an asylum.

One volunteer who provided the OED with countless quotation slips was William C. Minor, a schizophrenic person who was incarcerated at the Broadmoor Insane Asylum in Berkshire, England, after he fatally shot a man he (erroneously) believed had broken into his room. According to Murray, Minor was the dictionary’s second most prolific contributor, even outdoing members of the full-time staff.

8. J.R.R. Tolkien contributed to the OED, too.

In 1919 and 1920, J.R.R. Tolkien worked for the dictionary, where he studied the etymology of Germanic words beginning with the letter w, composing drafts for words like waggle and wampum. “I learned more in those two years than in any other equal period of my life,” Tolkien later said. (Years later, Tolkien spoofed his editors in a comic fable called Farmer Giles of Ham [PDF].)

9. The longest entry in the OED is for a three-letter word.

The most complicated word in the Oxford English Dictionary? Set. In the dictionary’s 1989 edition, the three-letter word contains 430 senses (that is, shades of meaning) and requires a 60,000-word definition. Other short words with endless definitions? Run (396 senses), go (368 senses), and take (343 senses).

10. The most popular edition of the OED was impossible to read with the naked eye.

Originally, the OED had a limited audience. Not only was a set of books expensive, it was also bulky and took up an entire bookshelf. In 1971, the Oxford University Press decided to publish a smaller, complete version that compressed nine pages into one. The text was so tiny that the two-volume book came with a magnifying glass. It quickly became one of the bestselling dictionaries on the market.

11. Digitizing the OED took a lot of work.

In the late 1980s, it took more than 120 typists, 55 proofreaders, and a total of 67 million keystrokes to digitize the entire contents of the Oxford English Dictionary. The process took 18 months.

12. Shakespeare isn’t the OED’s most quoted source.

The OED’s most quoted source is, in fact, the British daily newspaper The Times, which has 42,840 quotations (nearly 10,000 more than William Shakespeare). Coming in third and fourth are the Scottish novelist Walter Scott and the Philosophical Transactions of the Royal Society of London, respectively. When it comes to coining and introducing new words, Shakespeare isn’t first in that arena either; that honor belongs to Geoffrey Chaucer.

13. The last word in the OED is totally buggy.

Each year, about 2000 to 5000 new words, senses, and subentries are added to the Oxford English Dictionary. For years, the last word in the book was zynthum, a type of malty beer made in ancient Egypt. But in 2017, zynthum was usurped by zyzzyva, a type of South African weevil.

A version of this story ran in 2019; it has been updated for 2023.
