The word "nobleperson" refers to someone who is distinguished, grand, or honorable. Its antonyms, on the other hand, are the opposite of those characteristics. Words such as "ignoble," "villainous," "dishonorable," and "infamous" can be used to describe people who are not noble in behavior, character, or reputation. An ignoble person lacks honor or morality, while a villainous person is wicked or evil. Similarly, a dishonorable person lacks ethical standards and principles, while an infamous person is notorious or disreputable. To be considered noble, one must exhibit qualities such as integrity, bravery, and selflessness. Conversely, individuals who lack these qualities can be considered the antithesis of a nobleperson.
