Mostly indigenous languages have a deep connection with nature and its objects. Among these languages, Pashtu has a profound connection with nature. The speakers of the Pashtu language live in mountainous areas, one of the rich places on most earth species. Second, mountains resemble might and softness. Due to these features, Pashtu is the eco-friendliest language and thus has to abandon econaming in literature. This research contributes to highlighting the econaming concept in the Pashtu language. This research used Pashtu literature mostly spoken by ten Pashtu speakers. The face-to-face interview was conducted with Pashtu speakers more than 60 years of age. They have been asked to name connections with plants, animals, or things of nature. Then these names were recorded along with semantic meanings. The Ecocriticism approach is being used to analyse the data. By applying the Ecocriticism approach, this research examines the lexical noun items in Pashtu literature and reveals a profound connection between Pashtuns and nature. The Pashtu language exhibits a positive contribution towards nature preservation, with endangered species given a human-like soul. This study enriches the research content of the Ecocriticism approach and opens up new opportunities for future ecolinguistic studies.
