[1] Same or similar glossing (minus the grammatical point) in other lexica. The headword is first person plural, future, of the verb katasofi/zomai (cf. kappa 774). It must be quoted from somewhere: not independently attested in this form, but perhaps a mistake for the subjunctive katasofisw/meqa in Exodus 1.10 LXX. (See on this Photius kappa363 Theodoridis, citing Dindorf.)
[2] For this very rare verb, see Gregory of Nazianzus, Letters 190 and Severianus, De caeco nato 59.546; also Lexicon Syntacticum (Ai( suntiqe/menai diplai= sunta/ceis) 51.
