American Heritage® Deluxe brings two references together in one app: The American Heritage® Dictionary of the English Language and Roget’s II: The New Thesaurus. It is designed for writers, students, and word lovers who want both definitions and synonyms without switching apps.
The dictionary is the complete 2,074-page edition, with nearly 300,000 terms, more than 33,000 written examples and about 64,000 professionally recorded pronunciations. The front matter, appendices, and zoomable illustrations are all included. Roget’s II adds a full thesaurus, so after checking what a word means you can quickly find alternatives.
Both titles share Enfour’s fast search tools, including real-time look-up, wildcard searches, and cross-referencing. Enfour also offers a newer app based on the American Heritage® Dictionary, Fifth Edition.
