Phatic expression

Utterances which primarily serve a social function

In linguistics, a phatic expression is a communication which primarily serves to establish or maintain social relationships. In other words, phatic expressions have mostly socio-pragmatic rather than semantic functions. They can be observed in everyday conversational exchanges, as in, for instance, exchanges of social pleasantries that do not seek or offer information of intrinsic value but rather signal willingness to observe conventional local expectations for politeness.
