= Synagoge delta404; Photius, Lexicon delta818; and cf. Hesychius delta2751, where the two glosses are reversed. Also a comparable entry, according to Adler, in the Ambrosian Lexicon (1144).
The headword adjective could, in itself, be either neuter nominative singular or accusative singular in any gender, but the glossing resolves the ambiguity in favor of neuter singular, nominative or accusative. Outside lexicography this form is only attested in Basil of Caesarea, Homilies on the Hexaemeron 7.4 and 9.5. In general dush/nemos is attested first in Apollonius Rhodius (Argonautica 1.593) but not thereafter until the second century CE; Plutarch fr.82; Babrius, Mythiambi Aesopici 1.18 (both genitive singular). In the following centuries it appears in Basil, Nonnus and subsequently in medieval authors. For the antonym see epsilon 3471.
[1] The second gloss here (again under delta 1683) is unattested outside lexicography.
