How to Use this Online Dictionary

The dictionary of definitions is organized in multiple sections, with screens displayed after each word search is performed:

- Word definitions and examples are retrieved from the word search menu, providing different meanings and telling users what must be done in order to define the word(s) they are looking for.

- Thesaurus resources are provided to link words with their antonyms, provide related definitions, illustrate the origin of the words and find synonyms for the words. Images, hyponyms and hypernyms may also be available and are provided from external sources when applicable.

- A translation option is currently in beta testing. This option will enable the users to directly translate words from one language to another.

Dictionary of Definitions

In 1997, the Dictionary of Definitions, formerly known as Didef.com, became one of the first English dictionaries to be put online on the Internet. Originally based on Webster's synonym dictionary and Roget's Thesaurus, the site disappeared for a short period of time because of a domain name dispute. Today, this original word dictionary has evolved into a powerful and free online antonym and synonym dictionary, comprising hundreds of thousands of definitions.

Every month, some 12,000 visitors from all over the world use the Dictionary of Definitions for many different reasons including free word searches, free spelling activites, online thesaures lookup, or simply to obtain correct spelling of words. Its simplicity, and the elegance of its interface, make this web site one of the favorite online dictionarys on the net.

The Dictionary of Definitions is superior to many others because of its clean and visually appealing interface, as compared with other Internet dictionaries which are cluttered with invasive advertisements and pop-ups.

Dictionary definitions from no less than 33 major sources are available on this site, with topics ranging from medical dictionary terms, to legal terminology, bible references or slang jargon. Translations will be available later this year when 3 new sections are added for use by our users: a Spanish dictionary, a French dictionary and a Latin dictionary.
