This app contains The American Heritage® Dictionary of the English Language, Fourth Edition, the complete 2,074-page dictionary with nearly 300,000 terms. It also includes around 64,000 pronunciations recorded by native speakers and more than 33,000 written examples. A newer Fifth Edition app is also available from Enfour.

Enfour designed the app to make this large reference fast to use. Look-ups update as you type, wildcard pattern searches help with uncertain spellings, and a three-way cross-referencing search finds words that appear inside other definitions. A built-in spelling suggestion dictionary helps when you are not sure how a word is written, and internal hyperlinks let you move through related entries.

The complete front matter and appendices are included, making this a thorough desk dictionary that you can carry anywhere.
