摘要：The first role, which is usually considered for language, is data transfer. This information may be transferred by language through different techniques so that a group of linguists, who are known as pure linguists, assumes this role as the most essential role of language while they considered other roles as very trivial. But, another group attaches more value for role of language as social communication and deems it as infrastructural. The social linguists support from the latter theory and assume the communication only as one of the roles of language. Trudgill maintains that the language is not only a device for data exchange but it is deemed as a very important tool for communication and keeping contact with others (1974). But Lines (1977) distinguishes the communicative and informative concepts of language by attributing them to viewpoint of sender and receiver of message. In his opinion, the message is communicative when it is sent in order to make the receiver aware by the sender. On the other hand, if message includes communicative data for receiver it is considered as informative. Advertisement of goods is also of those items in which the informative role of language is merged in its social rolee and despite of the main objective of promotion that is giving the necessary and adequate information about the product, what is visible in practice consists of psychological effect and thus further communication with the customer and forcing the customer to purchase.
