Etiquette and manners are both critical to functioning in society. While both of these concepts involve rules of behavior, they are slightly different, and they involve different types of skills. They also vary from culture to culture, as standards of conduct are heavily based on cultural tradition and heritage.
Manners involve general behavioral guidelines, such as treating the elderly with respect and courtesy. Etiquette is a specific code of behavior, with an example of etiquette being knowledge of the proper mode of address for a Queen, which is, incidentally “Your Majesty.” In some societies, people regard etiquette as elitist and unnecessarily refined, but this is actually not the case. Many of the rules of etiquette are already practiced by people with good manners, and a demonstration of familiarity with etiquette and manners will mark someone as cultured, polite company.
