Explanation
Brethren is a fancy plural form of "brother" and is most often used in religious contexts. A monk might refer to other monks in a monastery as his brethren. Though it literally means "brothers," brethren frequently refers to members of the same religious community. You'll also see the word used more broadly today to refer to male members of fraternal organizations, or any group of people with close social ties. Thomas Paine used it to argue for democracy when he wrote, “The world is my country, all mankind are my brethren, and to do good is my religion.”
