Jeniffer is a feminine name that serves as an alternative spelling of Jennifer, which originated as a Cornish form of Guinevere, meaning 'white wave' or 'fair spirit.' This variation maintains the familiar sound while offering a slight distinction in written form. Jennifer became extraordinarily popular in the mid-20th century, particularly in the 1970s when it was the #1 girls' name in America for several years. While the traditional spelling remains more common, Jeniffer has maintained consistent usage among parents seeking a subtle twist on the classic. The name carries the same friendly, approachable qualities as Jennifer while potentially feeling slightly more unique due to its spelling.
