Final answer:
Manners or etiquette are the norms of good taste and social acceptability, encompassing rules of polite behavior in society.
Step-by-step explanation:
The norms of good taste and social acceptability are called manners or etiquette. These encompass rules of conduct dealing with dress, table manners, and general politeness within a society. They are considered important for the quality of life, and while often not as strictly enforced as laws or mores, violations of etiquette can result in social censure or being deemed impolite. Different cultures have varying norms, which can include both mores, or norms with moral significance such as honesty and laws against murder, and folkways, which are less stringent and relate to everyday behavior. What is considered appropriate etiquette can diverge significantly between societies.
