So you can often find a variety of language styles and ways of pronouncing them, because actually there is an emotional message to be conveyed, so that the meaning can be understood. One example of where the use of various languages is often found is the market. The market is a place for interaction between traders and sellers, so in the context of selling their products, traders in interacting with prospective buyers instinctively carry out various developments in the use of words and language styles, in order to attract the attention of prospective buyers. This study aims to describe the model of communication between sellers and buyers in traditional markets. To answer these objectives, a qualitative approach is used with descriptive methods.
