Of relatively recent origin and uncertain etymology. It is first recorded in the 19th century. It may be a shortened form of Belinda, an adoption of Spanish linda ‘pretty’, or a Latinate derivative of any of various other Germanic female names ending in -lind meaning ‘weak, tender, soft’. It was popular in the 20th century, especially in the 1950s.
English: from a vernacular form of the Late Latin personal name Dominicus ‘of the Lord’. This was borne by a Spanish saint (1170–1221) who founded the Dominican order of friars. In medieval England it may have been used as a personal name for a child born on a Sunday. As an English surname it is comparatively rare, and in the U.S. it has undoubtedly absorbed cognates in other European languages; for the forms, see Hanks and Hodges 1988.
