This corpus-based dictionary is designed as an aid for the advanced learners of Persian to master the meaning and usage of the most common words of contemporary Persian. The entries contain different types of information such as the formal and colloquial pronunciation of the headwords, their grammatical category, related derivations, collocations and idiomatic expressions. They are defined with simple and clear definitions using only 2800 words of basic Persian vocabulary, familiar to the advanced learners. Real examples extracted from a huge corpus (Persian Linguistic Database: PLDB) support the definitions and show how they are used in everyday language. Special graphical symbols readily show relative frequencies of the headwords which are often illustrated by pictures next to them and are occasionally referred to color illustrations in the appendix section. Several subject lists such as the limited defining vocabulary, common verbs with their infinitive, present and past stems, numbers, most frequent personal names for girls and boys, historical and geographical names are also included in the back matter as appendices.

The dictionary is published in printed and electronic format.
