Nobility refers to a privileged class of people — often receiving hereditary titles — also called the aristocracy. You know the type. They hang around manors and castles, or curry favor at court.
In the United states, there is no official class system, so there is no official noble class, or nobility. But nobility is also a synonym for nobleness — elevation of morals, ideals, or behavior. So if you have friends who always behave with generosity, honesty, and integrity, you may be surrounded by nobility — even if you don’t hang out with lords, baronesses, dukes, or ladies.
