Oxford Dictionaries Online is Oxford’s innovative dictionary and language reference service. A free dictionary (which includes a comprehensive current English dictionary, as well as up-to-date bilingual dictionaries in French, German, Italian, and Spanish) is available on the site for anyone to use; but subscribers to our premium current English dictionary site, Oxford Dictionaries Pro, get access to a wide range of extras:
- smart-linked, fully searchable content from Oxford’s largest modern English dictionaries and thesauruses
- more than 350,000 definitions and 600,000 synonyms and antonyms
- a vast bank of over 1.9 million example sentences, taken from real English
- ‘My Oxford Dictionary’ feature for creating your own profile and saving entries and searches
- comprehensive coverage of British, US, and World English - with audio pronunciations
- extensive sections with detailed writing, grammar, and spelling guidance
- specialist language reference resources for professional writers and editors
Oxford Dictionaries Online and Oxford Dictionaries Pro are updated quarterly, including some or all of the following: new words and senses, special features on language change, revised encyclopedic entries, and improved functionality.
To find out about planned changes, visit our what’s new section.
- The US version follows US English writing and spelling conventions, and features content tailored for countries that follow US English conventions
- The World version of the site is based on British English writing and spelling conventions
- Both versions of the site, however, feature exceptional coverage of English around the world, including British, Australian, Scottish, Irish, Indian, South African, US, and Canadian English – with each regional usage clearly labelled
You can choose whether you want to use the US or World version of the site. When you create your ‘My Oxford Dictionary’ profile (available to subscribers) the site will remember your preference, but you can still switch manually from the home page if you need to.
There is also a US and World version of our Word of the Day. The US version features US spelling and pronunciation, and the World version features British spelling and pronunciation. You can access either version on the home page of the site and switch between US and World version to hear the difference in pronunciation, and sign up for either version from the home page.
Below is a list of the resources on which the content of Oxford Dictionaries Pro is based. Many specially commissioned materials and articles are also included on the site, but not listed below. The premium site also includes 1.9 million sentences selected from the Oxford English Corpus.
