Prague linguistics has presented the theory of connection between normal and literal languages based on Jacobsen theories and distinguished the poetic role of language from its connective role. Followers of this school believed that the connective role of language included those of normal, routine, automatic, and normative. In this way, language acted just as a referent; however, the poetic role of language tends towards signs, symbols, and their significance. Writers of this research try to study the connective language of poems by Mohammad Ibne Ibrahim Al-Mousavi, known as Alavi Broujerdi (1272- 1362); he is one of the poets of fourteen centuries. This study has used an analytic- descriptive method. The findings showed that this poet explained his thoughts and senses truthfully and his emotions were displayed so much in his poems. A hidden pronoun in imperative verbs in this poem has no special address, but it can be used to address anyone reading this poem. The poet has used elements perceived by external and inward senses to help him transfer his message; this method can make an inseparable connection between the inside and the outside of global readers. By focusing on the literary role, Alavi Boroujerdi has actually neglected the connection between the linguistic and literary aspects and since the emphasis on the literary role is on the message, by using these literary works he wants to convince and delight the addresser.
