The word "righteous" refers to being morally right or justifiable. It is often used to describe actions, attitudes, or people that exemplify virtue, fairness, or integrity. A righteous person consistently adheres to ethical principles and seeks to do what is considered morally good.
The word "righteous" comes from Middle English "richeous," which is derived from Old English "rihtwisc," a combination of "riht" meaning "right" and "wisc" meaning "-ish" or "like." This term has its roots in the Proto-Germanic word "*rehtwiskaz."
