Delamarre, Xavier, “Dea Sunuχsalis”, Studia Celtica Fennica 11 (2014): 5–7.
There are dedicaces in the Bonn-Cologne region to a Goddess Sunuxsalis. It is proposed here a Celtic etymology of the theonym through a segmentation *Sūn(o)-uχs(o)-ali-, with Sūno- from *supno- or *swepno-. The meaning of the theonym would be ± 'She who fulfils (grants, exauces) high dreams'.
