Introduction: The term ‘defamiliarization’ which usually appears in FORMALISTIC works is, in fact, a major item in their literary theory, and it refers to the application of expressions and strategies to make discourse literary. In other words, it makes the perception of words unconventional, unusual and unfamiliar. The basic tenets of FORMALISTIC theories mainly rely on the CRITICISM of the ‘form’. In this view, form means any element which can create a cohesive composition in relation to other interrelated elements provided that each element plays its role in the whole system. Thus, every part of the text, like imagery, prosodic meter, rhyme, syntax, syllables, voiced and voiceless consonants, and figures of speech, constitutes the form. It focuses on intertextual elements and uncovers the defamiliarization realizations of the text. Indeed, it overlooks issues like the author’s character and social and historical contextual factors surrounding the literary work. On the other hand, linguistic forms and properties are analyzed so as to examine the cohesion and literary aspects of the text. Since its formulation by Shkolovsky, a Russian formalist critic, defamiliarization has attracted many critical formalism adherents. In other words, formalism embraces the Context Theory and analyzes the literary text features including its lexical items, grammatical structure, rhetorical devices and phonological properties. The term ‘context’ has attracted a lot of attention in modern linguistics. In general, a context can be viewed from both linguistic and extralinguistic perspectives. An extra-linguistic context refers to the outside of the text conditions affecting and crystalizing the author’s words. In addition to out-of-thetext factors, the linguistic function of each textual element at lexical, syntactic, semantic and phonological levels can be analyzed in relation to the linguistic aspects of the text and the way they affect the literary work. Methodology: The present study is conducted through a descriptive-analytical method and in a FORMALISTIC theoretical framework to show the linguistic and inner representations of defamiliarization in ‘Al-Hurria’ composed by Ahmad Matar. This piece of poem is composed of lexical items which conceptualize freedom. Results and discussion: The poet attempts to illustrate himself or any other free person as a driven-away captive distressed by the confinement sufferings. The first representation of defamiliarization in ‘Al-Hurriah’ can be seen in an overall perspective. It means that the poet gives such an uncommon picture of freedom that one can live a free life even in captivity. The purposeful selection of some lexical items has made the poet’s language distinguished and prominent. In addition, with respect to the defamiliarization features represented in the preceding analysis, it seems that the concept of freedom is depicted such that, in the depth of captivity and confinement, one can live a free life. Such a freedom cannot be interpreted as the liberation of man’s body from chains and shackles. It is, on the other hand, the faith crystalized in the character and nature of the liberated man, spreading over the other organs of his body in a way that even the most evident human emotions originating from sorrows and anguish, anxiety and mental confusion are conceptualized very differently from the way they are conventionalized in the native’s beliefs. In symbolic imagery, this concept shows itself as a drop of tear released from the prison of an eyelid as if destiny and the end of all captives ended in liberation from both material and spiritual imprisonment. Thus, defamiliarization offers a farfetched unconventional imagery of liberty. This is because the poet has revealed the concept of freedom as a fantastic idea to show that it can be perceived even in the depth of captivity. By using verbs with a special semantic load, a gentle and purposeful arrangement of words next to each other, and its coexistence with emphatic letters at the syntactic level, the defamiliarization intensity of the text of the poem has been increased. Also, in order to induce the sense of violence, suffocation and unpleasantness of captivity and the sense of pleasantness and continuity of freedom, the letters used in each word phonetically correspond to the content of the text. Conclusion: The results indicated that the concept of liberty and its confrontation with captivity is depicted unconventionally in this poem. The poet has used two different perspectives to depict the atmosphere that dominates the text. In the first point of view, which is based on an external view, a dark scene of the moment of arrest and the pushing of a captive is depicted for the audience. In this space, it seems that the tears flowing from the captive's eyes will affect every viewer who looks at him from the outside. On the other hand, by depicting the mental mood of a prisoner from an internal and psychological point of view, the atmosphere of the text moves toward openness and pleasantness. In this perspective, captivity is considered the same as freedom. The purposeful selection and arrangement of phonemes, lexical items and rhetorical devices tend to support defamiliarization throughout the text.
