What Is a Group of Nuns Called?

The New Collegiate dictionary states that the word superfluity has a 14th century origin. The linguistic source of the word can be found in the Latin term superfluus, the Anglo-French word superfluité and the Middle-English word superfluitee. A single nun, a woman who has made solemn vows to a religious order, is generally called a sister, though some religious orders also refer to her as mother or dame.
