Same entry in other lexica; references at Photius nu322 Theodoridis. The headword is nominative/accusative neuter plural of this adjective. It must be quoted from somewhere; Theodoridis suggests Euripides, Orestes 800 (web address 1).
See also nu 572 (same adjective but in masculine nominative singular, and with this and other glosses), nu 573 (the abstract noun formed from the same headword).
