The increasing popularity of the study of Persian (also known as Farsi, Tajiki or Dari) in the English speaking world, has created a need for a bi-directional Persian-English dictionary geared towards English speakers who are learning Persian. The features of the Persian-English / English-Persian Learner's Dictionary which make it unique are: Bi-directional: This is the first and only Persian-English/English-Persian dictionary in one volume which features both Persian and transliteration.

This dictionary provides a simple transliteration of the Persian word along with its equivalent in the Persian alphabet. Alphabetical order: In this dictionary, the alphabetical order in the Persian-English section is based on the English spelling. This makes it easy for the user who is not familiar with the Persian alphabet to find a word.

Entries: Approximately 18,000 entries covering both day-to-day and more specialised vocabulary. The Audience for this dictionary is: English speaking students of Persian.
