An interpersonal skill is any technical competence facilitating communication and interaction with others wherein interpersonal relationships and social rules are formed, expressed, and modified in non-verbal and verbal ways. The act of learning these interpersonal skills is known as sociability. Social awkwardness arises when a person does not learn how to develop these interpersonal skills. There are different types of social skills. They can be formal or informal, primary or secondary, universal or particular.
