Normative (or standard) refers to a set of guidelines or rules that define what is considered acceptable or typical behavior within a society or group. These standards help establish norms that influence how individuals interact, communicate, and make decisions. Normative standards can be found in various areas, including ethics, law, and social behavior. In the context of language, normative grammar outlines the rules for correct usage, helping speakers and writers communicate clearly. For example, the Chicago Manual of Style provides normative guidelines for writing and citation, ensuring consistency and clarity in published works.
