Merriam-Webster

• 1. Introduction

  ›

  Merriam-Webster is the oldest dictionary publisher in the United States, and its story begins not with a corporation but with a single man's obsession. Noah Webster spent two consecutive decades, starting in 1807, trying to capture the entire English language on paper. He learned 26 languages just to trace the origins of words. He believed Americans were speaking, spelling, and writing too differently from one another, and he set out to fix that. The questions his work raised are still alive today: who gets to decide how a language is spoken? What happens when the rules change? And how does a reference book become a cultural institution?

• 2. Webster's Grand Ambition

  ›

  Webster published his first dictionary in 1806, a smaller work called A Compendious Dictionary of the English Language. That was just the warm-up. He spent the following year beginning a far larger project, one that would consume the next twenty years of his life. He completed that work in 1825, finishing it during a year spent abroad at the University of Cambridge and then in Paris. The resulting dictionary featured 70,000 words, roughly 12,000 of which had never before appeared in any dictionary.

  Webster was a committed spelling reformer. He believed English spelling was unnecessarily tangled, and he used his dictionary as a platform to introduce American alternatives. Colour became color. Waggon became wagon. Centre became center. He also added words with no British counterpart at all, including skunk and squash.

  At 70 years old, in 1828, Webster finally published An American Dictionary of the English Language. The reception was a commercial disappointment. Only 2,500 copies sold, and the project left him in debt. He would have to wait until 1840 to see vindication, when a second edition published in two volumes proved vastly more successful.

• 3. The Merriam Brothers Step In

  ›

  George Merriam and Charles Merriam founded their company in 1831 as G & C Merriam Co. in Springfield, Massachusetts. They were in the book trade, and when Noah Webster died in 1843, they moved quickly. The brothers purchased the publishing and revision rights to Webster's 1840 dictionary from his estate, securing the foundation on which every Merriam-Webster dictionary since has been built.

  Four years after acquiring those rights, in 1847, they published a revised version of the dictionary. The main text remained unchanged, but new sections were added. A second update followed in 1859, this time with illustrations. The real transformation came in 1864, when Merriam published a greatly expanded edition that was the first to actually rework Webster's text. It retained many of his definitions and kept the title An American Dictionary, but it largely overhauled his original work.

  By 1884, the edition had grown to contain 118,000 words, described at the time as 3,000 more than any other English dictionary. In 1890, the company retitled its flagship publication Webster's International, and subsequent New International editions published in 1909 and 1934 expanded the vocabulary to over half a million words. The 1934 edition was later referred to as Webster's Second International, or simply "The Second Edition."

• 4. The Controversy of the Third

  ›

  In 1961, Merriam published Webster's Third New International, edited by Philip B. Gove. The edition immediately sparked public controversy. Many of the changes were presentational, stripping out punctuation Gove considered unnecessary and using phrases instead of complete sentences where those were sufficient.

  The more contentious shift was philosophical. The Third New International moved away from prescriptivism, the tradition of telling readers how language ought to be used, and toward describing American English as it was actually spoken and written at the time. Critics felt this abandoned the dictionary's role as an authority. Defenders argued that language is a living thing, not a set of rules handed down from above.

  The main text of that 1961 edition has remained virtually unrevised since its publication. It is the foundation beneath subsequent collegiate editions, but it stands apart as the last time the company undertook a full overhaul of the unabridged dictionary. In 1983, the ninth collegiate edition, titled Webster's Ninth New Collegiate Dictionary, made changes that distinguished the collegiate line as its own entity rather than simply an abridgment of the Third. Among those changes was the inclusion of the date of the first known citation of each word, documenting its entry into English.

• 5. Building the Citation File

  ›

  Before any word enters a Merriam-Webster dictionary, it has to be found in actual use. Editors spend roughly an hour each day reading print sources, ranging from books and newspapers to advertisements and product packaging. Their goal is to observe how individual words are used in the wild and to preserve those usages in a central citation file.

  That file now contains more than 16 million entries. Millions of the older citations are recorded on physical 3-by-5 cards, the earliest dating back to the late 19th century. Since 2009, all new citations have been recorded in an electronic database. The breadth of sources editors examine matters as much as the volume. Formal and informal publication alike get equal attention, because a word that appears only in academic journals tells a different story than one showing up in product packaging.

  In 1998, the Collegiate Dictionary reached its twelfth edition, with the most recent published on the 18th of November 2025. The 2003 eleventh edition contained over 225,000 definitions and more than 165,000 entries.

• 6. Authority and Influence

  ›

  Merriam-Webster's influence extends well beyond its own sales. The Chicago Manual of Style, followed by a wide range of U.S.-based book publishers and magazines, designates Merriam-Webster as its preferred source for general matters of spelling. The Manual notes that it normally opts for the first spelling Merriam-Webster lists, which makes that ordering a quiet but consequential editorial decision.

  In 1964, the company became a subsidiary of Encyclopædia Britannica, Inc. Its name changed to Merriam-Webster, Incorporated in 1982, first reflected publicly with the publication of the ninth collegiate edition in 1983. Before that edition, publications had used "A Merriam-Webster Dictionary" only as a subtitle.

  In 1996, Merriam-Webster launched its first website, offering free access to an online dictionary and thesaurus. On the 16th of February 2007, the company announced a mobile dictionary and thesaurus service developed with Ask Me How, allowing users to access definitions, spelling, and synonyms via text message. The company also runs a Word of the Day service and an Open Dictionary, a wiki that lets subscribers submit new words and definitions for consideration.

• 7. A Voice in the Culture

  ›

  Merriam-Webster has maintained an active social media presence in recent years, using its platform to weigh in on public events through the lens of language. Its approach is dry and exact: when a political figure misuses a word, the dictionary tends to post the definition. In November 2021, it used a tweet that went viral to subtly accuse Kyle Rittenhouse of fake crying during his trial.

  The company's willingness to engage with politics through dictionary jargon earned it a following far beyond the audience that might otherwise seek out reference books. The underlying logic is consistent with the Third New International's legacy: words are used in real contexts, and tracking how they are used is not a neutral act.

  Unicode version 4.0, published in 2003, finally supported the phonetic symbols specific to Merriam-Webster's dictionaries; earlier versions going back to Unicode 1.1 in 1993 had accommodated standard IPA symbols but not the company's proprietary set. Until full Unicode support arrived, Merriam-Webster's online services used a less specific set of ASCII characters to represent pronunciation, a technical workaround that lasted for years. That gap between the printed page and the digital screen is a small reminder of how much infrastructure is required to carry a 70,000-word dictionary into the modern era.
