- Extensive hyperlinked dictionary with 150,000 entries.

- Fully integrated dictionary, thesaurus, wikipedia browser (internet connectivity is required for accessing wikipedia) and rhyming dictionary.

- Customizable definitions let you select what you want to see. You can display synonyms, antonyms (opposite words), hypernyms (more general words), hyponyms (more specific words) and related words (category words).

- The only dictionary in the app store with advanced high quality Text-to-Speech capability to say defined words out loud (tap the 'speaker' button to hear the word).

- E-mail button to e-mail word definitions, allowing you to access them anywhere.

- Intelligent word search and spell check

- Optional translation of words being looked up to Spanish, Italian, French, German and Japanese. Translation uses Google translate and requires an internet connection.

Wiki Restarts


On my iPhone 4, I have a problem when I move between my word processor and the DICTIONARY Wiki.
The DICTIONARY Wiki restarts the incumbent search.
This is a problem because I often have used multiple layers of links inside the Wiki.
Thank you for all you do.

Dictionaries aren’t important anymore!
