The etymology needs more details. Regarding this: epanastrophe is made up of 4 elements stemming from Greek/Ancient Greek. I don't know if the etymology of the English word is from Ancient Greek or Modern Greek -- this is something the editor would need to examine -- but the break down of epanastrophe is this: ἐπι- (or Modern Greek derivative: επι-) + ἀνα- (or Modern Greek derivative: ανα-) + στρέφω + -η which gives ἐπαναστροφή (or Modern Greek: επαναστροφή). ἐπι- and ἀνα- also form the composite prefix ἐπανα- (meaning "again", see: el:επανα- for further details) so the primary etymology is either going to be ἐπι- + ἀνα- + στροφή, ἐπανα- + στροφή, or ἐπι- + ἀναστροφή depending on how the word was coined or conceived (something that again the editor will need to examine).
