These examples illustrate the meaning of the word as 'undamaged, unaffected by wounds to body or spirit, unpolluted by extraneous matter' or 'in a state not affected by previous experiences or failures'. The adjective is not derived from the root of mixing seen in kera/nnumi but either from the word for 'blemishes' (see alpha 833) or from a root of damaging seen in kerai+/zw and khrai/nw. Chantraine connects it with kerai+/zw, but indicates that it has been influenced by kera/nnumi. He finds the relationship between a)ke/raios and a)kh/ratos unclear.

[1] Same gloss (for which cf. under alpha 833), according to Adler, in the Ambrosian Lexicon.

[3] Iamblichus fr. 16 Habrich.
[4] Polybius 15.11.11 (web address 2; cf. 6.24.9, 9.31.1,6: a common phrase for the mental state, particularly of fresh troops, that has not yet been affected by loss and wounds).
[5] Polybius 3.70.9 (web address 3).
[6] Polybius fr. 96 Büttner-Wobst, known only here (and epsilon 1520); cf. 23.4.11, 38.7.8. Büttner-Wobst notes (p. 527) that Ursinus (Fulvio Orsini, 1529-1600) deemed it Polybian, but that Schweighäuser doubted the attribution of this fragment to Polybius. Walbank suggests (p. 751) that a possible context for the fragment is Polybius 25.2.14 (web address 4). If this is correct, then the fragment details the moment in the war (179 BCE) of Eumenes (epsilon 3579) and Ariarathes (alpha 3869) against Pharnaces of Pontus (cf. OCD(4) s.v Pharnaces I; Pontus: Barrington Atlas map 87 grid B4) when the latter offered a bribe to Seleucus (IV Philopator, c.218-175 BCE (assassinated), cf. OCD(4) s.v. Seleucus(4)) so as to draw Seleucid troops into the conflict. Although Seleucus might have acquiesced, per the Suda, he apparently had second thoughts and did not break his existing agreement with the Romans (Walbank, p. 274; Gruen, p. 646).
