Said to be a Calque of Paelignian [Term?] for "above the plain"; first element from super (“above”), second element could possibly be from a late Proto-Indo-European substrate *aikwo (“plain”), though the kw > p typical of Italic languages would be expected; perhaps borrowed through Messapic. Compare the Italic placenames Aecae Aeculanum, Aequum Tuticum, and Aequum in Illyria.
