Benign Shares Its Latin Root With Many Words
Benign traces back to the Latin adjective benignus, which was formed from bene, meaning "well," and the verb gignere, "to beget"—that is, "to produce or create." Gignere is also the root of such English words as genius and germ, and even shares distant ancestry with kin. The meanings of benign range from describing an absence of danger or harm to that which shows kindness or is gracious or wholesome.
