Possibly a variation of Deja, meaning already
Daijha is a modern American name, likely a creative phonetic spelling of the French word 'dΓ©jΓ '. It gained some usage in the late 20th century as part of a trend of adding unique prefixes or suffixes to established sounds. Because it is a modern creation, its roots are more stylistic than etymological.
