Oxford Deluxe combines two of Oxford’s largest English references in a single app: the Oxford Dictionary of English, Second Edition (ODE) and the Oxford Thesaurus of English, Second Edition (OTE). Together with extensive recorded audio, this makes it one of the most complete Oxford English resources available on a mobile device.
Both titles are included in full, along with their appendices and reference material. Searches update as you type, wildcard queries help with uncertain spellings and word games, and entries are hyperlinked so you can jump between a definition and its synonyms in a tap. Around 72,000 pronunciations recorded by native British speakers let you hear words as well as read them.
Extra tools include iCloud-synced bookmarks with notes, an online fallback for archaic words and new slang, and an AI Teacher that can give deeper explanations to learners of English in many languages.
