Instead of an impersonal passive verb with the accusative and infinitive as subject, Greek often uses the personal passive construction, the accusative becoming the nominative, subject to the leading verb.
Thus, Κῦρος ἠγγέλθη νῑκῆσαι Cyrus was reported to have conquered instead of ἠγγέλθη Κῦρον νῑκῆσαι it was reported that Cyrus had conquered, and δίκαιός εἰμι ἀπελθεῖν I am justified in going away instead of δίκαιόν ἐστιν ἐμὲ ἀπελθεῖν it is right for me to go away. English sometimes has to use the impersonal construction in place of the Greek personal construction (cp. 2107).
a. The personal construction is more common with λέγεται, ἀγγέλλεται, ὁμολογεῖται and other passive verbs of saying (regular with passive verbs of thinking); with συμβαίνει it happens; with ἀναγκαῖος necessary, ἄξιος worthy, δίκαιος just, δυνατός possible, ἐπιτήδειος fit, etc., followed by a form of εἶναι, instead of ἀναγκαῖον, ἄξιον, etc. Thus, ὁ Ἀσσύριος εἰς τὴν χώρᾱν αὐτοῦ ἐμβαλεῖν ἀγγέλλεται
the Assyrian is reported to be about to make an incursion into his country C. 5.3.30, πολλή τις ἀλογίᾱ ξυμβαίνει γίγνεσθαι
much absurdity would result Phil. 55a, δίκαιος εἶ εἰπεῖν
it is right for you to speak S. 214c, τὴν αἰτίᾱν οὗτός ἐστι δίκαιος ἔχειν
it is right for him to bear the blame 18.4. Both constructions together: σοὶ γὰρ δὴ λέγεται πάνυ γε τεθεραπεῦσθαι ὁ Ἀπόλλων, καί σε πάντα ἐκείνῳ πειθόμενον πρᾱ̓ττειν for Apollo is said to have been greatly served by you, and (it is said) that you do everything in obedience to him C. 7.2.15. Cp. 2104.
N.—δῆλός ἐστι and φανερός ἐστι take ὅτι or the participle (2107); δῆλόν ἐστι and φανερόν ἐστι take ὅτι, not the infinitive.
