ἰὼ! ἆ ἆ! ἒ ἔ, παπαῖ παπαῖ! ἰὼ πόποι! ὀτοτοτοῖ πόποι δᾶ!
Aeschylus’ Cassandra has quite a spectacular vocabulary when it comes to exclamations. I wonder if anyone is aware of a discussion of Greek exclamations…
“Internet” told me the Greeks still say po po and po po po when they’re surprised about something. I wonder if it’s derived from πόποι. (Chantraine’s Dictionnaire étymologique de la langue grecque didn’t mention such a possibility though 
)
