Once Upon a Time is a selection of seven Persian folktales. These tales ‎have been selected for intermediate and advanced learners of the ‎Persian language. A simple and easy language has been used to ‎rewrite these stories with the intent to stay as close as possible to the ‎narrative tone of the original texts. ‎The selection starts with shorter and simpler stories, so that the ‎readers could eventually elevate their reading and comprehension ‎skills. ‎The new words in each story have been underlined and their English ‎definitions have been provided under an index at the end of each ‎story.‎ It is hoped that this selection would be helpful to those who are ‎studying the Persian language and encourages them to explore the ‎richness of the Persian literature beyond the pages of this book. ‎
