Want to take The Living Arabic Project's dictionaries wherever you go? Download the mobile app Lughatuna! It costs a little bit, but purchasing it supports the project so more cool dictionaries and new features can be added.
This site is always growing. What started out as a simple word list on a student’s desktop has evolved into two of the largest dialect dictionaries ever written for the Egyptian and Levantine dialects with plans for additional dialects and a growing Classical Arabic (Fusha) dictionary, all run on a uniquely structured database designed for Arabic’s diglossia. To make it practical and accessible, there are apps and learning resources appropriate for all levels of users.
Arabic is hard and complex, but also rich and deep. Imagine learning tools that map out Arabic for you and help you learn it. That’s what this site is. It has dictionaries for Egyptian, Levantine, and Classical Arabic, and it has apps and learning resources to help you access the language.
These dictionaries are more than just a list of words, they are guides to the Arabic language. The uniquely structured database allows users to search by Arabic word, English word, and Arabic root. There are also thousands of examples to show users how to properly use words and listing common phrases and proverbs.
