Conversation is a form of interactive, spontaneous communication between two or more people. Typically it occurs in spoken communication, but some written exchanges may also be referred to as conversations. The development of conversational skills and etiquette is an important part of socialization. The development of conversational skills in a new language is a frequent focus of language teaching and learning. Conversation analysis is a branch of sociology which studies the structure and organization of human interaction, with a more specific focus on conversational interaction.
