Meaning

Boni is a widespread Italian surname derived from the personal name Bono (feminine Bona). According to E. De Felice, the name partly continues the Latin personal name Bonus, meaning "good", but more commonly developed during the Early Middle Ages from the vernacular adjective buono or bono, used as a nickname for a person considered kind, virtuous, or of good character.

The surname therefore originated as a descriptive nickname highlighting positive personal qualities and later became a hereditary family name. The form Boni represents a patronymic or family form meaning "the descendants of Bono" or "the family of Bono".

V. Blunda proposes an alternative interpretation for some Sicilian families. According to this view, the surname may derive from the Greek term boynìon, meaning "hill", originally functioning as a nickname for someone who lived near a small elevation in the landscape. Blunda presents this explanation specifically for the Sicilian context.
