The Great Dehkhoda Dictionary is a complete and free Persian dictionary app that displays the largest number of vocabulary for you. It is the greatest and most important work of Ali Akbar Dehkhoda, which took more than 40 years of his life to complete. The dictionary includes meanings, interpretations, and historical explanations of a significant number of Arabic loanwords entered into Persian.

The Great Dehkhoda Dictionary includes a large part of the literary vocabulary of the Persian language, along with their meanings and applications in poetry. However, this dictionary does not contain much of the Persian vocabulary and technical terms that came to the Persian language domain more than a decade after the dictionary was written.

It is important to note that this app is online and requires internet access. The app's data volume is close to 400 megabytes. The app is completely free, but it does display ads within the program.
