= Hesychius epsilon3683, Lexica Segueriana 224.3, and (according to Adler) the Ambrosian Lexicon (1263).
Outside lexicography, the headword -- third person singular, aorist indicative active, of e)kkwma/zw -- occurs only in Euripides, Andromache 603 (web address 1), and the specific pejorative meaning attached to it here is surely extrapolated from that context (where it refers to Helen's elopement with Paris). The scholia to the line assign it a wider array of possible meanings: e)cexw/rhsen, e)cwrxh/sato, e)cebakxeu/qh , ei)s ai)sxu/nhn metatra/ph ('departed', 'danced out', 'went on a bacchic frenzy' 'turned to shameful behavior').
