Politeness is a social behavior that serves to facilitate interactions between individuals and that has an important role in the maintenance and success of communications. Although it is a universal concept, the rules of politeness have specific forms in each society and these forms are reflected in different ways in each language. Among these are the forms of politeness and all other kinds of expressions that are used to express politeness directly or indirectly. The studies on the concept of politeness have led to the conception of a "politeness theory" and the categories of negative and positive strategies have been established. Positive politeness strategies are defined as strategies which are used to maintain the face of communicating individuals by performing acts that are used to express politeness directly without any threat; while negative politeness strategies aim to perform acts of politeness that are used to soften the effects of certain acts that can negatively influence the participants. The various communication situations that are likely to be carried out within the society require generally the use of these two types of strategies. The aim of this study is to treat the theory of politeness and its basic notions according to the formulaic expression of politeness in Turkish, which are a part of the Turkish culture. Following this objective, the formulaic expressions have been studied to define those which can be employed to produce positive and negative politeness strategies. Then, they have been studied from a pragmatics point of view to define their speech act values. This study, therefore, brings a new point of view on one of the important components of the structure of the society which is politeness and its linguistic manifestation in Turkish.
