There is a mutual relationship between language and social phenomena which highlights the need to comprehend the different language functions. Understanding these functions is the task of language sociologists. Michael Halliday, (1973 AD) one of the theorists in the area, divides the communicational functions of language into 7 classes: instrumental, regulatory, interactional, personal, heuristic, imaginative, and informative. He believes that this pattern can be traced in all types of language functions. Since the typewritten manuscripts have a key role in expressing cultural details in which drivers act the role, the present study aims atinvestigating the language system governing Arabic and Persian car written manuscripts based on Halliday's7 functions of language in order to discover similarities and differencesbetween their language systems. The results indicate that the typewritten manuscripts in these two languages reflect a significant part of Arabic speaking and Persian speaking societies’ common values, and their literature follows a specific language pattern, therefore, statistical population of drivers’ literature content analysis will offer considerable help regardinganthropology and ethnography of each society. Statistical studies show that, in Arabic and Persian typewritten manuscripts, the most frequency is related to personal function and the least frequency is related to heuristic function. Accordingly, the considerable frequency of personal function indicates that Arabic speaking and Persian speaking societies are influenced by social condition in contemporary era.
