Aénor (also Aenora, Ainora; the spelling Aénor suggests an original trisyllabic pronunciation) was a feminine given name in medieval France.[1] It is likely the origin of, and by the later Middle Ages was replaced by, the name Eleanor (Alienor).
It arose as a latinization of an earlier Germanic name, via the form Adenordis (Aanordis, Anordis, Anor).[2] Use of the name seems to be mostly confined to the 12th century; before that, it would have retained its original form (Anordis or similar), and after 1200 it had been mostly ousted by its replacement Eleanor. The form Adenordis is recorded in the 1090s.[3] It may itself be a corruption of Adamardis,[4] apparently a feminine form of Ademar.
