Nouns and personal names ending in –εύς –ῆϝος are unique to Greek, and have often been deemed pre-Hellenic in origin simply on account of the lack of Proto-Indo-European (PIE) correspondences. Our failure to find convincing etymologies for βασιλεύς, ἑρμηνεύς, and βραβεύς has itself contributed to this view. However, we should hesitate, for general reasons, to posit pre-Hellenic origins for these words, since viable explanations both of βασιλεύς and of ἑρμηνεύς (if not of βραβεύς) lie near to hand. Although the explanation (...) of βασιλεύς that will be proposed below still presents difficulties, I believe that it improves on previous attempts. (shrink)
