I assume in the above case περὶ αὐτῆς is where the second accusative should be?Luke 4:38 Ἀναστὰς δὲ ἀπὸ τῆς συναγωγῆς εἰσῆλθεν εἰς τὴν οἰκίαν Σίμωνος ⸆. πενθερὰ δὲ τοῦ Σίμωνος ἦν συνεχομένη πυρετῷ μεγάλῳ καὶ ἠρώτησαν αὐτὸν περὶ αὐτῆς.
In this case, Is τί οὖν standing in for the second accusative?John 1:21 καὶ ἠρώτησαν αὐτόν ⸆· ⸂τί οὖν; σὺ Ἠλίας εἶ;⸃ °καὶ λέγει· οὐκ εἰμί. ὁ προφήτης εἶ σύ; καὶ ἀπεκρίθη· οὔ.
In this case λέγοντες isn't accusative?Matt. 15:23 ὁ δὲ οὐκ ἀπεκρίθη αὐτῇ λόγον. καὶ προσελθόντες οἱ μαθηταὶ αὐτοῦ ⸀ἠρώτουν αὐτὸν λέγοντες· ἀπόλυσον αὐτήν, ὅτι κράζει ὄπισθεν ἡμῶν.
I have a few of the more advanced grammars such as Wallace, but I can't see a section that would help me understand this better. Wallace does mention ἐρωτάω on page 604, but he doesn't mention it has a double accusative. It does mention two forms of double accusative on page 181 but I don't see how his description "person-thing" or "object-compliment" fits this above example. Am I missing something?
