Eponym (Nambakhsh): Eponym (Nambakhsh): A kind of rhetoric in Persian language

The eponym is a noun and an adjective that has become a concept. In fact, the concept has become one with the object, and nowis used in as aconcept that has been accepted by the collective subconscious.Unlike Metaphor, eponym is not used in literary language; rather it is mostly used in common language; and contrary to metaphor, which requires a symmetrical understanding, eponym is rooted in the unconscious group of a particular people or culture.In fact, eponyms are stereotyped metaphors which understanding them depends on cultural similarity. Such words have been widely used in language; but in Persian, so far no research has been done on this genre. This research seeks to introduce eponym as a genre and also to classify such nouns based on their semantic domain and type of its usage.The method of this research has been qualitative and its data has been done based on descriptive-analytical method and using library study tools. The result of this division is putting eponyms in eight different groups: religious and non-religious, animals and people, positive and negative, politics and place. On the other hand, they have been put in six categories: names of persons, animals, place, accessories related to religious and mythical elders, and in the meanings of virtual worlds and adjective. The most frequent eponyms in Persian are special nouns that have become adjectives such as Iblis and the Antichrist. Some eponyms are animals that have become adjectivessuch as carnivores and hyenas. Some place names have also become adjectives; like Sahrayeh Karbala & Resurrection.
