Don’t rummage through the bookshelf or lug around a tome: utilize a mobile version of a highly trusted, reliable, and informative resource: the Oxford Dictionary of English.

Using this version is a bit different from flipping through A to Z pages: start the app, and you can immediately look up the word you want using the search bar. If you are unsure of a word’s spelling, say it out loud using the microphone! You can also use your device’s camera to capture text and look it up. If you need other options, tap the sidebar menu icon for Recent, Favorites, Sharing, and more. Avoid malapropisms and... um... that condition where you can’t think of the word... with a dictionary at your fingertips!

▲ Get more than just a definition: IPA guide, part of speech, and word origin help you learn English.

▲ If you are struggling spelling a difficult word, start typing and see what shows up in Suggestions.

In this dictionary app, each entry features the part of speech as well as an IPA (International Phonetic Alphabet) pronunciation guide — great for English-language learners or teachers. You can also learn the origin of given words or word parts. See your selection used in example sentences (identified in italics) to help you know how to use it correctly. Also, clickable links in a term’s definition will direct you to other useful words and their meanings.

Whether you are an aspiring writer or a second-language learner, instant access to a trustworthy and functional English dictionary will greatly improve your vocabulary.

It's okay, but I thought it would have been better. I sometimes have bad cell tower reception in my area, and it looks like this dictionary doesn't have offline mode! Also had some problems with the audio as well. A bit disappointed..
