Britannica is proud to introduce Al-Jazem, a world leading Arabic-English-Arabic dictionary. Al-Jazem provides users with a dictionary, translation service, pronunciation guide and thesaurus for words as well as idioms, expressions, phrases and sentences. Al-Jazem is a free service and is updated daily to keep in tune with changes in the Arabic and English languages. What sets Al-Jazem apart from other Arabic-English dictionaries is the natural language processing technology, developed by Encyclopædia Britannica. The technology enables understanding the morphology (the way the words are constructed) of both the Arabic and the English languages.
