The headword -- here in the masculine accusative singular or neuter nominative/accusative singular -- has the same or similar glossing in other lexica (references at Photius alpha378 Theodoridis), and must be quoted from somewhere. It is a particular favourite of the late epic poet Nonnus of Panopolis (on whom see generally OCD(4) s.v., p.1020). See also under alpha 900. LSJ entry at web address 1.
