Did You Know?
Benediction, benefactor, benefit, benevolent, and benign are just some of the English words that derive from the well-tempered Latin root bene, which means "well." Benign came to English via Anglo-French from the Latin benignus, which in turn paired bene with gignere, meaning "to beget." Gignere has produced a few offspring of its own in English. Its descendants include congenital, genius, germ, indigenous, and progenitor, among others. Benign is commonly used in medical contexts to describe conditions, such as noncancerous masses, that present no apparent harm to the patient. It is also found in the phrase benign neglect, which refers to an attitude or policy of ignoring an often delicate or undesirable situation that one has the responsibility to manage.
