After the release of the Oxford Dictionary app last week, Oxford Learner’s Thesaurus app has now been launched on iPhone and iPad.

The app was released by multi-platform dictionary applications developer for mobiles, tablets and PCs, Paragon Software Group.

The app helps with understanding the differences between similar words in written and spoken English, enabling learners of English to enrich their vocabulary and to find the right words to say exactly what they mean.

Each entry has a group of 3-10 synonyms with the meaning clearly explained, together with additional help with, for example, grammar and register. An example sentence shows how each synonym is used in a particular situation. Notes highlight and explain synonyms that are particularly close in meaning or easily confused, so the user chooses the right word for their context.

The app offers over 17,000 synonyms and opposites with clear explanations, an alphabetical index, making it easy to find the word users are looking for and guidance on the most frequently used synonym.

There are 30 pre-loaded topics with useful word lists users can add to or edit, and the option for users to create and organise their own lists of favourite words. Real British and American voices pronounce the words and their synonyms.

The is a ‘Did you mean…?’ function and wildcard search, which allows users to find a word if they don’t know the spelling.

The app requires iOS 7.0 and later.
