In response to Joseph Worcester's groundbreaking dictionary of 1860, A Dictionary of the English Language, the G. & C. Merriam Company created a significantly revised edition, A Dictionary of the English Language. It was edited by Yale University professor Noah Porter and published in 1864, containing 114,000 entries. It was sometimes referred to as the Webster–Mahn edition, because it featured revisions by C. A. F. Mahn, who replaced unsupportable etymologies which were based on Webster's attempt to conform to Biblical interpretations of the history of language. It was the first edition to largely overhaul Noah Webster's work, and the first to be known as the Unabridged.
