Already; from the French phrase déjà né meaning already born
Dejanee is a modern American coinage, likely inspired by the French phrase 'déjà né' (already born) or as a creative elaboration of the name Deja. It gained some usage in the late 20th century alongside other names beginning with the 'De-' prefix. The name carries a sense of destiny or a feeling that the child was always meant to be.
