Download one of the most intuitive and easy to use mobile dictionaries with quick access to millions of words, laid out in a unique format by WordNet.

Entirely revised and updated to include the most comprehensive and accurate picture of the English language today, the Advanced English Dictionary and Thesaurus represents the authority of dictionary apps.
The intelligent search features, leading to a rich word list with special language notes, cross-curriculum words and the prompt navigation - all contribute to your unique user experience. Nouns, verbs, adjectives and adverbs are grouped into sets of cognitive synonyms, interlinked by means of conceptual-semantic and lexical relations. In addition to the straightforward definitions the dictionary shows how each word is linked to other words in terms of synonyms, opposites and similar words, but also hyponyms and hyperlinks within the group.
The WordNet concept had become the staple of quality language apps:
* Straightforward and precise definitions of over 140,000 with more than 250,000 links and 1.4 million words
* Synonyms, antonyms, similar and related words to help improve your writing and speech
* Hypernyms (more generic words), hyponyms (subordinate words) and meronyms (part names)
* Examples illustrate how words are used and show typical constructions and collocations
* Offline audio support (internet connection is NOT required)
This app is tailored to professionals, students, and academics, as well as anyone who needs a comprehensive and authoritative dictionary of current English at work or at home.

'THE' best!👌 🌟🌟🌟🌟🌟

If you're studying at any level at all, are a lover of crosswords or just a lover of 'correct' English (Australian/UK in my case) - skip the iPhone Apps that are 'supposed' to be 'the best' or 'frequently downloaded' and are also free *but bombard you with Ads.* - and go straight for the "Advanced English Dictionary and Thesaurus"!!!
In writing (my preference is 'academic' style), choosing not just a good word, but 'THE' best word that carries weight and will emphasise your intended meaning, is the key to writing clearly and well and THIS dictionary is the only one that I use, for that very reason.
BTW: They also have a Windows App that I ALWAYS use on my PC... verrrrrrry handy and easy to use!
So that THIS App + the PC App, work well together if that's what you're looking for!!
"Pssst... it's also 👍 great for those hard-to-find words when you hit a difficult crossword clue!"

What you are looking for - 2020

The free version has all the same contents as the paid version but without the ads, the paid version is literally the same as the free version but without annoying ads and things, the price is 1.50 so you’re not exactly breaking bank getting ads removed, if you can stand ads, then download this and you’ll have the best free dictionary app there is at the moment, if you’re like me and hate ads passionately, then you pay one dollar fifty to have all ads removed and the app completely unlocked.

Just buy the app anyways, it’s literally one dollar fifty. 🤷🏻‍♂️

Fabulous for new Australian residents or citizens

I learn a new word every day😍Sometimes the words are to well known and the learning effect is rather a reminder about spelling or pronouciation🙂 My son is struggling with his English test for his skilled migration, even so he and his family have previously worked in Oz on a skilled visa and their Spoken English is very good. He is now working in Dubai for the same campeny🤓 and communication is in English but the tests are in writing and no phones/ dictionaries/ Thesaurus allowed.
