The name Jenessa is a modern English name, a combination of 'Jen', a short form of Jennifer, and the popular suffix '-essa'. Jennifer itself is of Cornish origin, derived from the Welsh name Gwenhwyfar, meaning 'white phantom' or 'white fairy'. The suffix '-essa' is often used to create feminine forms of names or to add a lyrical quality. Jenessa, therefore, carries connotations of femininity, modernity, and a connection to the traditional name Jennifer.
