Webster's Third New International Dictionary
Webster's Third New International Dictionary is an unabridged dictionary of the English language, published in 1961 by G. & C. Merriam Company and edited by Philip Babcock Gove.[1] Containing approximately 450,000 entries derived from over 10 million citation slips documenting actual usage, it represented a comprehensive revision of its predecessor, retiring obsolete terms while incorporating more than 100,000 new words and senses reflective of mid-20th-century American English.[1] The edition's defining innovation was its strict adherence to descriptive linguistics, eschewing prescriptive judgments on correctness in favor of empirically recording how words were used in print, which eliminated traditional usage labels for substandard or informal variants.[2] This approach, costing $3.5 million and involving 757 editor-years of effort, positioned the dictionary as a scholarly tool aligned with structural linguistics but ignited fierce backlash from linguists, journalists, and educators who decried it as excessively permissive, particularly for neutrally treating contested forms like ain't and slang without condemnation.[1][2] Despite the uproar, which filled newspapers and scholarly journals, the dictionary's empirical methodology influenced subsequent lexicography, establishing descriptivism as the standard for major unabridged works.[1]
