Which term describes strongly enforced societal norms that may provoke reactions if violated?

The term that describes strongly enforced societal norms that may provoke reactions if violated is mores. Mores are the essential and characteristic customs and conventions of a community. They are often seen as vital to the continued existence and welfare of a society, which is why violations of mores typically lead to significant repercussions or societal disapproval.

Mores often dictate moral behavior and can cover a range of issues, including laws, ethical conduct, and social expectations, which shape a community's values. For example, behaviors that harm others or violate fundamental rights are often viewed as violations of mores and can lead to serious sanctions or ostracism.

In contrast, folkways refer to informal norms that govern everyday behavior but do not carry the same level of moral significance. While taboos are also serious prohibitions, they are extremely strong social prohibitions against certain behaviors that are considered so unacceptable that they evoke strong feelings of disgust or horror. Customs are broader practices and traditions followed by a group, but they may not be as strictly enforced as mores. Thus, mores are the most appropriate term for strongly enforced societal norms.
