Detta

Detta is an English and Irish diminutive that can shorten names ending in -detta or -etta, such as Bernadetta, Henrietta, or Benedetta. Since those source names have different origins, Detta has no single literal meaning. It also became an independent familiar name in the nineteenth and twentieth centuries. Notable bearers include Irish-British politician Detta O’Cathain and Irish cellist and music educator Detta Danford. The intended full-name source must be established from the individual bearer.
