NOUNS: THE CASES
502 A noun (or pronoun) in the same case with another, and denoting the same person or thing, is an appositive if added directly, a predicate if added by means of a verb. Both appositive and predicate noun may be in any case, according to the construction of the primary noun:
Αὐδῶμαι δὲ παῖς Ἀχιλλέως, Nεοπτόλεμος I am callsd the son of Achilles, Neοptolemos. S. P. 240 f. (Here Neoptolemos is an appositive to παῖς, which is a predicate noun, agreeing with the understood subject of αὐδῶμαι.
