Another example of this predicate nominal with a non-copulative verb that I have logged away is Acts 26.5:
They're not particularly common, but also not uncommon. I have never really seen a robust discussion of the predicate usage of nominals (either nouns or adjectives) with non-copulative verbs.
Smyth 910-12 is the only place I have really found much on it at all, and that is really slim.
a. A predicate substantive is a substantive forming part of the predicate and asserting something of its substantive: Περικλῆς ᾑρέθη στρατηγός Pericles was elected general, εἵλεσθε ἐκεῖνον πρεσβευτήν you elected him envoy L. 13. 10.
b. A predicate adjective is an adjective forming part of the predicate and asserting something of its substantive: ὁ ἀνὴρ δίκαιός ἐστι the man is just, ἐνόμισαν Περικλέᾱ εὐτυχῆ they thought Pericles fortunate.
911. A predicate substantive or adjective may often be distinguished from an attributive (912) in that the former implies some form of εἶναι be. Thus, πρεσβευτήν and εὐτυχῆ in 910. After verbs signifying to name or call, εἶναι is sometimes expressed (1615).
912. Attributive Adjective.—An attributive adjective is an adjective simply added to a noun to describe it, and not forming any part of an assertion made about it: ὁ δίκαιος ἀνήρ the just-man.
Have there been any studies on the parameters of this sort of usage?
