The headword is the perfect middle/passive participle, masculine accusative singular or neuter nominative/accusative singular, of the verb pari/hmi; cf. pi 592, pi 593, pi 606, and see LSJ s.v. It must be quoted from somewhere, probably (as Theodoridis [below] notes) from one of its two appearances in Euripides (Orestes 881, Heracles 1043).
[1] The gloss is the same form of the verb xauno/w. Same glossing in the Synagoge, Lexica Segueriana 331.30, and Photius, Lexicon pi352 Theodoridis; cf. alpha 1896, chi 150.
