The term 'social skill' refers to the ability to interact with others in a socially appropriate manner. Two words that can be used to describe this concept are 'TACT' and 'savoirfaire'. TACT is a four-letter word that means having a sense of what is appropriate to say or do in a given situation. Savoirfaire is an eleven-letter word that means having the knowledge and experience to handle any situation with grace and confidence. Together, these two words encompass the idea of social skill.
