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.
Irish and English: 1. nickname for a brave or powerfully built man, from Middle English stout ‘steadfast’. 2. from the Old Norse byname Stútr ‘gnat’, denoting a small and insignificant person. 3. possibly also a habitational name from a minor place named with the Old English element stūt ‘stumpy hillock’, which is found as a component in various Devon place names.
