Pragmatic language is a component of social communication.
Social communication encompasses the following components:
pragmatics—communication that focuses on goal-consistent language use in social contexts (N. Nelson, 2010)
social interaction—communication that occurs between at least two individuals
social cognition—an understanding of the mental and emotional states of self and others, social schemes, and social knowledge that beliefs and values cause social events, expected socially appropriate behavior and consequences of inappropriate behavior
language processing—internal generation of language (expressive), and understanding and interpretation of language (receptive)
