Ἀντήρεις

[Meaning] placed-opposite, meaning [sc. in this instance] equal to the dirges; a metaphor from those rowing, whenever they row equally and the ship is not thrust to one side. So "answering" [means] striking in response to the dirges; for Electra in mourning was striking her chest for each [lament]: "hear many answering blows on my bloodied chest."¹
But [note also] a)nth=ris, [genitive] a)nth/ridos, and it means window.²
