Same entry in other lexica. No form of the headword (which appears to be the nominative singular masculine form) occurs elsewhere, apart from the derivative entry in ps.-Zonaras 904. Perhaps a back-formation from eu)frosu/nh ("happiness") or from eu)/fron (the neuter nominative/accusative singular of eu)/frwn), which could easily be mistaken for a masculine accusative or neuter nominative/accusative form of the headword. Alternatively, Theodoridis (on Photius s.v.) supports ms V's eu)/foros.
