Previous literature either penned down the philosophical and mystic attributes of Ghani Khan’s poetry, or the literary qualities of his poetry, but perhaps no study has undertaken cognitive linguistic analysis of his poetry. The present paper attempts to carry out cognitive semantic study of the concepts of life and death in Ghani Khan’s poetry from cognitive linguistic perspective. Conceptual metaphor theory will be used to analyze the poetic language of Ghani Khan’s Kulyat in order to find out the conceptual schemas, which are used in description of life and death in his poetry. This theory holds that everyday language as well as poetic language is generated, processed and comprehended by the conceptual metaphors in human conceptual system.The analysis shows that Ghani Khan has used ten (10) key conceptual metaphors in description of life and death with slight cultural deviations in nine poems on the titles of life and death. This paper has also found that since Ghani Khan has used the key conceptual metaphor of LIFE IS A DAY, he has also used LIFE IS TWO DAYS drawing upon the conceptualization of life in Pukhtun culture. This paper finds that the figurative language in Ghani Khan’s poetry is based on the conceptual metaphors, and it recommends further research on Pashto everyday language and poetry from cognitive-linguistic and cognitive-semantic perspectives in order to validate the various tenets of conceptual metaphor theory through cross-cultural research.
