This study analyzed a sample of online Arabic-English-Arabic specialized dictionaries of the Arabization Center in Morocco, the Arabic Language Academy in Cairo, the Saudi Terminology Databank (BASM), School Arabia glossaries, Dictionary Bay, and Babylon, to identify their entry design, entry components, breadth of coverage, whether they include the most recent terms, accuracy of translational equivalents and inclusiveness of meanings given. The study revealed several shortcomings of those online specialized dictionaries such as limited coverage, inaccuracy and inclusiveness of some meanings and slow up-dating. Some recommendations are given to improve the practicality and usefulness of online Arabic-English-Arabic specialized dictionaries to translation students.
