The headword, extracted from the quotation given, is the aorist active participle, masculine nominative singular, of the compound verb kataspei/rw (kappa 782).
[1] Sophocles, Ajax 1005, with a gloss from the scholia vetera thereto. Compare also the scholia to Ajax 1000 in Dindorf (below, p. 226.23–24): o(/swn lupw=n a)formh\n dou/s ("How much distress you have given occasion to"). In this scene, Teucer laments the suicide of his half-brother Ajax and the hopeless situation it has created for himself. The preverb kata- should perhaps be seen merely as an intensifier. Cf. Kamerbeek (below ad loc.): "not 'having strewn over me', but 'having sown for me'." Also, compare LSJ s.v. 1, citing this line, and 2.II. Other uses of the verb: Euripides, Hercules 469; Plutarch, Theseus 3.2, Demetrius 4.2, etc.
