An archaic term of address or title, possibly relating to a lady or woman of rank; extremely rare and obsolete.
Possibly from Old French or Scandinavian origins, related to 'domna' or 'donna' (lady). The exact linguistic path is unclear.
Domnei is so archaic that it barely exists in the historical record—it's a linguistic ghost that suggests medieval English borrowed more from Scandinavian languages than we usually realize.
