ὕβριστος
From LSJ
English (LSJ)
η, ον,
A = ὑβριστικός, wanton, insolent, outrageous, ἔργον Pherecr.162; ὕ. χρῆμα (sc. ἡ γυνή) Pl.Com.98:—hence Comp. ὑβριστότερος Hdt.3.81 (v.l. ὑβριστικώτερος), X.Cyr.5.5.41, Pl.Lg. 641c: Sup. ὑβριστότατος Ar.V.1303, X.An.5.8.22, Mem.1.2.12, Pl. Lg.808d.—In AB368 (where Pherecr. and Pl.Com. are cited) we are told that ὕβριστος is of the same type as Superlatives like βέλτιστος, κάλλιστος, κράτιστος, etc.; in which case ὑβριστότερος, -ότατος would have to be regarded as doubled forms of comparison:— ὑβριστός oxyt. is cited in EM697.56.
