Merriam-Webster: The History of America's Dictionary

Introduction

When Americans say "the dictionary," they almost invariably mean a Merriam-Webster dictionary. For nearly two centuries, the Merriam-Webster name has been synonymous with the authoritative recording of American English—the go-to reference for spelling, pronunciation, meaning, and usage. Yet the story of how a small Springfield, Massachusetts publishing firm came to dominate American lexicography is as dramatic and fascinating as any business saga, complete with fierce rivalries, cultural controversies, and transformative reinventions.

The history of Merriam-Webster is, in many ways, the history of American English itself—a story of how a young nation defined its linguistic identity, debated the boundaries of proper usage, and ultimately embraced the creative dynamism that makes English one of the world's most vibrant languages.

The Merriam Brothers Acquire Webster's Legacy

When Noah Webster died in 1843, his heirs faced a dilemma. The great dictionary needed ongoing revision to stay current, but the family lacked the resources and expertise to manage such a project. In 1843, George and Charles Merriam, brothers who ran a successful printing and bookselling business in Springfield, Massachusetts, purchased the rights to Webster's dictionary for $3,000 and the assumption of Webster's debts.

The Merriam brothers were not scholars—they were businessmen—but they had the shrewd judgment to invest heavily in making the dictionary better. Their first major decision was to hire Professor Chauncey A. Goodrich of Yale, Webster's own son-in-law, to oversee a thorough revision. The 1847 edition corrected many of Webster's etymological errors, updated definitions, and added new vocabulary, producing a work that was substantially improved over the original while maintaining the Webster brand and philosophy.

The Merriams also made the bold decision to price the dictionary affordably. Where Webster's original had been expensive and exclusive, the Merriam editions were marketed aggressively to schools, families, and businesses. This democratization of the dictionary—making it a household item rather than a luxury—was key to establishing the Webster name as the default American language reference.

The Dictionary Wars

The mid-19th century saw fierce competition in American lexicography, often called "the Dictionary Wars." The Merriams' principal rival was Joseph Worcester, a lexicographer who had actually worked for Webster before striking out on his own. Worcester's A Dictionary of the English Language (1860) was considered by many to be more conservative, more elegant, and more aligned with British usage than the Merriam-Webster editions.

The rivalry between the Webster and Worcester camps became intensely personal and sometimes unscrupulous. Both sides placed advertisements attacking the other's product, solicited endorsements from prominent figures, and lobbied state legislatures and school boards to adopt their dictionary as the official reference. Newspapers covered the competition like a sporting event, and the American public found itself drawn into debates about spelling, pronunciation, and the proper role of a dictionary.

The Webster forces ultimately prevailed, largely because the Merriam company invested more heavily in revision and marketing. The 1864 Merriam-Webster edition, edited by Noah Porter, was so clearly superior to Worcester's latest offering that the competition effectively ended. By the 1870s, Merriam-Webster had established the dominance in the American market that it retains to this day.

The Unabridged Tradition

The crown jewel of the Merriam-Webster line has always been its unabridged dictionary—the largest, most comprehensive single-volume dictionary of American English. The major milestones in this tradition include:

• 1847: The Merriam revision of Webster's 1841 edition—the first under the new ownership.
• 1864: An American Dictionary of the English Language, Unabridged, edited by Noah Porter, with 114,000 entries.
• 1890: Webster's International Dictionary, reflecting the dictionary's growing engagement with world English.
• 1909: Webster's New International Dictionary, with over 400,000 entries.
• 1934: Webster's New International Dictionary, Second Edition (often called "Webster's Second"), containing 600,000 entries—the largest dictionary ever published at that time.
• 1961: Webster's Third New International Dictionary—the most controversial edition, which we'll examine below.

Webster's Third: The Most Controversial Dictionary

The publication of Webster's Third New International Dictionary in 1961, edited by Philip Gove, sparked one of the fiercest cultural controversies in American intellectual history. Gove's editorial philosophy was descriptive rather than prescriptive: he believed the dictionary should record how English was actually used, without making judgments about correctness. This led to several changes that outraged traditionalists.

The most controversial decisions included removing the label "colloquial" (which Gove felt was misunderstood as meaning "incorrect"), including slang and informal language without deprecatory labels, citing contemporary sources (including advertisements and sports writing) alongside literary quotations, and removing the encyclopedic content that had been a popular feature of Webster's Second.

The backlash was swift and intense. The New York Times declared that the dictionary would "accelerate the deterioration" of the English language. The Atlantic Monthly published a blistering review. Critics accused Gove of abdicating the dictionary's responsibility to maintain standards of good English. The controversy became a proxy war in a broader cultural debate about authority, tradition, and the nature of language itself.

In hindsight, Gove's descriptive approach was ahead of its time and aligned with the principles that now guide mainstream linguistics and modern lexicography. Webster's Third is now recognized as a landmark work of scholarship, though the controversy it generated permanently altered the relationship between dictionaries and the American public.

The Collegiate Dictionary

While the unabridged dictionary is the scholarly flagship, the Merriam-Webster product that most Americans actually use is the Collegiate Dictionary. First published in 1898, the Collegiate condenses the best of the unabridged dictionary into a single portable volume suitable for students, writers, and general reference.

The Collegiate has been through eleven numbered editions (the most recent is the Eleventh, published in 2003) and is the bestselling hardcover book in American publishing history. It is the official dictionary of the Associated Press, the American Psychological Association, and many other organizations. In Scrabble tournaments, the Merriam-Webster Official Scrabble Players Dictionary (derived from the Collegiate) is the definitive word authority in North America.

Digital Transformation

Like all reference publishers, Merriam-Webster has undergone a radical digital transformation. The company launched its website, merriam-webster.com, in 1996, making its dictionary freely available online. This was a bold and prescient decision that sacrificed potential subscription revenue in favor of reaching the widest possible audience.

The online dictionary is now one of the most-visited reference sites in the world, attracting over 100 million monthly visitors. It offers not just definitions but pronunciations (with audio), etymologies, usage notes, word history articles, quizzes, and the popular "Word of the Day" feature. The Merriam-Webster app extends this access to mobile devices, making the dictionary available anywhere at any time.

Merriam-Webster in the Social Media Age

Perhaps the most surprising chapter in Merriam-Webster's history has been its transformation into a social media phenomenon. The company's Twitter (now X) account, in particular, has gained millions of followers by combining lexicographic expertise with timely cultural commentary and gentle humor.

Merriam-Webster's social media team has developed a distinctive voice: authoritative but approachable, educational but entertaining, and occasionally pointed in its commentary on public figures' use (or misuse) of language. When politicians coin or mangle words, Merriam-Webster often posts relevant definitions or usage notes that go viral. This approach has made the dictionary brand relevant to younger audiences who might never have picked up a physical dictionary.

The "trend" feature on the Merriam-Webster website, which shows which words are seeing spikes in lookup activity, has become a real-time barometer of American cultural and political life. When a major news event occurs, the trending words on Merriam-Webster tell the story of how the public is trying to understand what's happening—a fascinating intersection of language, news, and collective curiosity.

Word of the Year and Cultural Impact

Since 2003, Merriam-Webster has announced an annual Word of the Year, based on lookup data from its website. Past selections—including "pandemic" (2020), "vaccine" (2021), and "gaslighting" (2022)—capture the preoccupations and anxieties of their respective years. The Word of the Year announcement has become a widely covered media event that reinforces Merriam-Webster's position as the authoritative voice on American English.

Beyond the Word of the Year, Merriam-Webster regularly adds new words to its dictionary in batches, with each addition garnering media attention. These additions—from "doomscrolling" to "rizz"—demonstrate that the dictionary remains a living document, continuously evolving to reflect the language as it is actually spoken and written by millions of Americans.

Merriam-Webster Today

Today, Merriam-Webster (a subsidiary of Encyclopaedia Britannica, Inc. since 1964) continues to serve as America's most trusted language reference. Its editorial team of professional lexicographers maintains the tradition of evidence-based, descriptive dictionary making that stretches back to Noah Webster himself—while embracing the digital tools and platforms that make the dictionary more accessible and relevant than ever.

The journey from Noah Webster's handwritten manuscript to a mobile app with millions of users is a remarkable story of adaptation and reinvention. Through dictionary wars, cultural controversies, and technological revolutions, the Merriam-Webster name has endured because it represents something that Americans value deeply: an authoritative, trustworthy, and accessible record of the words that define their lives.
