Same or similar entry in other lexica. The headword is imperfect active of kwqwni/zw, first person singular or third person plural. It must be quoted from somewhere -- but is perhaps (especially given the active gloss) misquoted: Hesychius has middle e)kwqwni/zonto, which Latte reasonably claims as extracted from the Septuagint. (He cites 1 Esdras 4.63; see also Esther 3.15.)
