WordWeb is an international English dictionary and thesaurus program for Microsoft Windows, iOS, Android and Mac OS X. It is partly based on the WordNet database.[1][2]



The thesaurus is integrated into the dictionary. Under each definition, various related words are shown, including:

Users can also actively improve the dictionary and thesaurus by submitting errors (such as missing words, phrases, or more senses for existing entries) and enhancement requests.



There are two WordWeb versions: the free version, which does not have the word list, search, anagram, or customization features; and the paid version, WordWeb Pro.

WordWeb 5 added the ability to list entries from three online sources: Wikipedia, Wiktionary, and WordWeb Online. These details appear in three separate tabs. Version 6 added audio pronunciations and support for third-party Oxford and Chambers add-on dictionaries.

WordWeb 7 was mainly a content upgrade, with revised definition and sound databases, but also had significantly updated one-click support for the latest browsers and 64-bit programs. Other changes included updated audio pronunciations, improved one-click integration with other programs, better one-click 64-bit and Windows 8 program support, keyboard hotkeys for Bookmark menu items, and auto-detect support for the latest third-party Concise Oxford and Merriam-Webster dictionary add-ons.

As of version 7, WordWeb required Windows XP, Windows Vista, Windows 7, Windows 8, or Windows 10.

WordWeb 8 includes one-click and keyboard lookup, including in Mozilla Thunderbird and Firefox without browser plugins.[3] Support for Windows XP was dropped.[4]

Open-source alternative


No version of WordWeb (including Pro) is available for Unix, however, it can be used with Wine. Artha, a similar program that includes some of WordWeb Pro's features, is available for both Linux and Windows; a port to Macintosh is promised.[5]



Use of the free version is subject to license terms.[6] However, it may be used by an educational institution (free of cost) for their students, even if they violate said terms.



WordWeb is regionalized, with specific dictionaries for Australian, British, Canadian, American, Irish, New Zealand, South African, and Indian English.
