One of the problems of Persian writing is the question of writing and including the noun or adjective "Prepositional" construction sign in words the written form of which end in a silent h which is in fact a short vowel equivalent to /e/ (kasra ).The difference between the two ways of writing the intermediary consonant /y/( ) at the end of the word with a last silent h , completely as or with the sign on the silent h is rooted in the controversy between the traditional and modern approaches of writing. The present study is about to study into the following subjects: an analysis and criticism of both the above approaches, a survey of the history of the intermediary /y/( ), recognizing its phonetic significance and its role in making and adding new syllables, and finally a conclusion about the more convenient way to write it. It is possible that the outcome of the present study will provide us with a unique form of writing of the case in different texts like books, articles, newspapers, journals and electronic texts.
