A Universal and Critical Dictionary of the English Language: To which are Added Walker's Key to the Pronunciation of Classical and Scripture Proper Names, Much Enlarged and Improved; and a Pronouncing Vocabulary of Modern Geographical Names

First published in 1846, this dictionary represents Joseph Emerson Worcester’s significant contribution to American lexicography during the mid-19th century. Worcester, a noted scholar and rival to Noah Webster, crafted this work to provide a comprehensive, scholarly resource that emphasized traditional orthography and pronunciation. It emerged during an era of intense competition among American lexicographers to define the standard of the English language as it evolved in the New World.

The volume is recognized for its meticulous inclusion of 'Walker's Key,' a classic guide for the pronunciation of classical and scripture names, which Worcester expanded to provide greater utility for students and educators. By incorporating a pronouncing vocabulary of modern geographical names, the dictionary served as an essential reference tool for the period's emerging middle-class readership. It was widely praised for its balance and accuracy, establishing Worcester as a primary authority before the eventual dominance of the Merriam-Webster standard.
