A magical spirit or genie, often portrayed as a character who grants wishes, popularized by the TV show "I Dream of Jeanie."
From the Arabic 'jinn' (a supernatural being), Jeanie became an English spelling variant used in American popular culture, particularly in 1960s television.
The spelling 'Jeanie' actually shows how English borrowed from Arabic mythology and then Hollywood repackaged it—the original jinn from Islamic tradition became a blonde American housewife in a bottle, which tells you something hilarious about cultural adaptation.
