عنوان مقاله [English]
One of the language's functions is the literary function. It is the spot of joint of the linguistics and literature. In the literary function, the focus is on the message; so the language of this message distinct of the standard language. The linguists explain this Foregrounding in two ways: escape the standard language that is named Deviation and adding the some rules to it that is named Extra regularity, in three levels: meaning, form and formal realization. The Deviation near the speech to the poetry and the Extra regularity verse it. In this short text, we pay to the most obvious Foregrounding, Deviation, in the Az in Avesta book; because it shows the Akhavan's art. In addition to so many Deviations forward to the Extra regularity in the Akavan's poetry, meaning Deviation is rather than the other kinds of Deviation. This kind contains the Figurative language and meaning Rhetoric topics that increase the imagination. Especially the Simile and Metaphor, two forms of poetic images, have used greatly. Then the temporal Deviation, the use the archaic words, is seen plenty; so we see that the other kinds of Deviation is found rarely; because these reduce the word's glory. Instance is found in the Akhavan's poetry too, that is untitled or isn't dependent on the mentioned kinds exactly.
