The American Heritage Dictionary of the English Language

The American Heritage Dictionary of the English Language (AHD) is an American dictionary of English published by Boston publisher Houghton Mifflin, the first edition of which appeared in 1969. Its creation was spurred by the controversy over the perceived permissiveness of the Webster's Third New International Dictionary. The third edition included over 350,000 entries and meanings. James Parton (1912–2001) was a grandson of the English-born American biographer James Parton (1822–1891). He was the founder, publisher and co-owner of the magazines American Heritage and Horizon, and was appalled by the permissiveness of Webster's Third, published in 1961. (Webster's Third presented all entries without labeling them correct or incorrect.) Parton tried to buy the G. and C. Merriam Company so that he could undo the changes. When that failed, he contracted with Houghton to publish a new dictionary. The AHD was edited by William Morris and relied on a usage panel of 105 writers, speakers, and eminent persons chosen for their well-known conservatism in the use of language. However, Morris made inconsistent use of the panels, often ignoring their advice and inserting his own opinions. The AHD broke ground among dictionaries by using corpus linguistics for compiling word frequencies and other information. It took the innovative step of combining prescriptive information (how language should be used) and descriptive information (how it actually is used). The descriptive information was derived from actual texts. Citations were based on a million-word, three-line citation database prepared by Brown University linguist Henry Kučera. For expert consultation on words or constructions whose usage was controversial or problematic, the American Heritage Dictionary relied on the advice of a usage panel. In its final form, the panel comprised nearly 200 prominent members of professions whose work demanded sensitivity to language.
