μέγιστος, as in “φίλος μέγιστος” ( Ph. 586, Ai. 1331) simply, ‘greatest’ friend; not, ‘most powerful.’
τυγχάνει, without “ὤν”: cp. 313, 1457: Ai. 9 “ἔνδον... τυγχάνει” . Ast collects some ten examples from Plato; a few are subject to the doubt whether “ὄν” or “ὤν” has not dropped out after a like termination; but that does not apply to (e.g.) Hipp. Ma. 300 A “ἡ δἰ ἀκοῆς ἡδονὴ...τυγχάνει καλή” , or Tim. 61 D “τυγχάνει...δυνατὰ ἱκανῶς λεχθῆναι” .
δορυξένων: a word applied by the tragedians to a prince or chief who is in armed alliance with the head of another state: see on O. C. 632.
