standard Substitution In The Iftiaal Form And Its Role In Achieving Assimilation According To Sibawayh

Abstract

This research paper aims to clarify the nature of one of the Arabic phonetic phenomena that aim to achieve vocal harmony and facilitate pronunciation that is represented by the phenomenon of substitution. Such phenomenon is considered one of the chapters dealt with by the ancient Arab linguists in the various topics of their books, which were characterized by digression. Although substitution is regarded as a phonemic topic, studies the sounds of the word and its similarity, convergence, and homogeneity, it is concerned at the same time with the structure of the word since it replaces a letter with another place and it achieves similarity at the pronunciation and grammatical levels. Accordingly, this paper tries to reveal this phenomenon and its related rules in one of the Arabic fundamental blogs in Sibawayh’s "book" as a source from which the researchers took each according to their field of specialisation, sound, morphology, dictation, grammar, and eloquence. Hence, this study attempts to know the phonetic and morphological laws that are updated for substitution, by showing the link between the sounds of the word and its structure.
