The Oxford Dictionary of English, Second Edition (ODE), is Oxford’s largest single-volume English dictionary, and this Enfour app includes the complete, unabridged text together with around 72,000 pronunciations recorded by British English voice actors.
Because the full book and audio are installed on your device, the dictionary works offline. Search results update as you type, wildcard searches help with unknown spellings and word puzzles, and the three-way cross-referencing search finds words in headwords, definitions, and other entries. Appendices and front matter are hyperlinked, and bookmarks with notes can be synced through iCloud.
Further tools include an online fallback search for archaic words and new slang, and an AI Teacher that provides deeper explanations for English learners in many languages. Other apps can also search the dictionary and return to where they started, through Enfour’s round-trip linking support.
