In a landmark move, Merriam-Webster is preparing to release the 12th edition of its renowned Collegiate Dictionary in November 2025. This update marks the first time in 20 years that the company has unveiled a new version of its iconic reference work.
The upcoming Collegiate Dictionary will feature a wealth of new content, including over 5,000 additional words and 1,000 new phrases and idioms. Some of the notable additions include modern terms like "cold brew," "farm-to-table," "rizz," and "dad bod." This expansion reflects the evolving nature of language and the way we communicate in the modern era.
Despite Merriam-Webster's significant digital presence, with over a billion website visits per year, the company remains committed to the physical book format. In fact, Merriam-Webster President Greg Barlow stated that the new Collegiate Dictionary will be "the finest" they have ever published, and a "volume to cherish" for book and dictionary enthusiasts.
Interestingly, the company's digital transformation has been a major driver of its success, with revenue growing by nearly 500% over the past decade. However, Barlow emphasized that the physical dictionary remains the "heart" of the business, underscoring the enduring appeal of the printed word.
