Which term refers to polite and proper conduct in social interactions?

The term that refers to polite and proper conduct in social interactions is etiquette. Etiquette encompasses the established rules and norms that guide behavior in specific social situations, often focusing on aspects such as respect, consideration, and appropriate communication styles. This includes understanding how to greet others, the appropriate way to behave during meals, and the expectations for interactions in formal settings.

While courtesy, protocol, and manners do relate to social behavior, they each focus on different aspects of conduct. Courtesy usually refers to acts of kindness or polite behavior towards others, but it may not cover the full range of social expectations that etiquette entails. Protocol refers to formal procedures or rules that are particularly important in official or diplomatic contexts, focusing more on formality rather than general social interactions. Manners is a broader term that encompasses etiquette but can sometimes refer to more informal behaviors rather than the specific rules and conventions that are part of etiquette. Therefore, etiquette is the most precise term to describe the polite and proper conduct expected in social interactions.
