[1] Headword and gloss are feminine nominative singular. Likewise, according to Adler, in the Ambrosian Lexicon, but other lexica (e.g. Hesychius omicron152) have neuter plurals. Either way, the headword must be quoted from somewhere.

See also the scholia to Lucian (6.12 Rabe), on the occurrence of the headword in the accusative plural in Phalaris 1.10.
