Functionality of identical ending syllable in form and structure of Ghazals of Hafez

The poet's choice of any word or phrase is effective not only in a line but also throughout the poem. If we look at the choice of a word or phrase repeated as an identical ending syllable in every verse, we find out the importance of choosing it by poet and the need for comprehensive proportionality of identical ending syllable with the whole poem. Due to the importance of choosing the identical ending syllable, I have studied the role and function of the identical ending syllable in ghazals of Hafez based on formalist and structuralist theories. I have examined functionality, value and rule of identical ending syllables of Hafez beyond the verse and in form and structure of ghazals. The result of this study shows that Hafez has chosen identical ending syllables which often fit with the theme, elements, texture and overall structure of the ghazal. Sometimes identical ending syllable is a tool in his hands to use it in difficult situations to express something that there is no possibility of expressing it with a nonpoetical word. Sometimes the basis of choosing identical ending syllable fits with the structure of ghazal in order to create humor. Sometimes the meaning of identical ending syllable is in contrast with some parts of the content and other words in the context of poem creating new semantic features.
