κράτιστος — krátistos
κράτιστος, κρατίστη, κράτιστον, superlative of the adjective κρατύς (κράτος) (from (Homer) Pindar down), mightiest, strongest, noblest, most illustrious, best, most excellent: vocative κράτιστε used in addressing men of conspicuous rank or office, Act 23:26; Act 24:3; Act 26:25, (Otto, De ep. ad Diognetum etc. Jena 1845, p. 79ff, and in his Epist. ad Diognet. Leips. edition, p. 53f, has brought together examples from later writings). Perhaps also it served simply to express friendship in Luk 1:3 (as in Theophrastus, char. 5; Dionysius Halicarnassus, de oratt. 1; Josephus, Antiquities 4, 6, 8), because in Act 1:1 it is omitted in addressing the same person. Cf. Grimm in Jahrbb. f. deutsche Theol. for 1871, p. 50f.
