Apposition to a Sentence.—A noun in the nominative or accusative may stand in apposition to the action expressed by a whole sentence or by some part of it.
a. The appositive is nominative when a nominative precedes: ἐμέθυον· ἱκανὴ πρόφασις
b. The appositive is accusative, and states a reason, result, intention, effect, or the like: ῥί_ψει ἀπὸ πύργου, λυγρὸν ὄλεθρον
εὐδαιμονοίης, μισθὸν ἡδίστων λόγων
N.—The appositive accusative is often cognate ( cross1563 f.): ὁρᾷς Εὐρυσθέα_, ἄελπτον ὄψιν
