American Heritage Dictionary 5

The American Heritage® Dictionary of the English Language, Fifth Edition, is one of the most respected references for American English, and this app brings the complete text to iPhone and iPad. The edition was the result of a decade of work by lexicographers and usage experts and added thousands of new words and senses.

Enfour’s app goes beyond a simple word list. Searches update as you type, wildcard patterns help when you are unsure of a spelling, and three-way cross-referencing indexes make it easy to find words hidden inside definitions. Detailed etymologies link to the dictionary’s root appendices, and professionally recorded audio lets you hear how words are pronounced.

For rare words and the latest slang, an optional online fallback search fills the gaps. The app is free to download, making it an easy way to keep a trusted American dictionary in your pocket.
