The quality of being kind, gentle, and not harmful; the state of being benign rather than malicious or dangerous.
From Latin benignus 'kind, gracious, favorable' (bene- 'well' + -ignus 'born/disposed'), through Old French benignité. The word entered English in the 13th century and originally meant both moral goodness and medical harmlessness.
Benignity is why doctors call non-cancerous tumors 'benign'—the word literally means they won't harm you, which is why this medical term comes directly from a Latin word meaning 'kindly disposed' and 'well-born.'
