(Entry lacking, Adler reports, in ms F.)
The unglossed headword is the perfect middle/passive infinitive of periori/zw (cf. pi 1221, pi 1222, delta 1579, epsilon 1905, etc.). There are a handful of attestations of this form in late Greek; perhaps the most likely to have found its way to the Suda is Gregory of Nyssa, De opificio hominis PG 44.201.38, where it serves as an articular infinitive.
