The headword is a feminine noun in the nominative (and vocative) singular. In the quotation given it occurs in the dative plural. See already phi 554 for the accusative plural, and generally LSJ s.v.
[1] Although translated here as a plural, the first glossing noun is singular in number, the same form as the lemma; see LSJ s.v. ko/mh and kappa 1993. The second gloss is a feminine noun in the nominative singular; see LSJ s.v. and theta 500. The headword is similarly glossed in Hesychius, Etymologicum Magnum 797.56 (Kallierges), and ps.-Herodian, Partitiones 145. For the second gloss, Adler also cites Lexicon Ambrosianum 433.

She also reports that ms G replaces the particle te by tis (someone) and transmits an alternative form of the imperfect indicative active, third person singular e)ko/mei of the contract verb koma/w (Ionic kome/w), I let my hair grow long.]
