I couldn’t either so I cheated and used Perseus project to find it.
According to this it’s from κατά and ἕ?δω. I couldn’t find the compound verb in my dictionary (but them I can’t seem to think straight so it may be somewhere there and I just missed it).
The verb ἕ?δω is, according to my dictionary of ionic origin and quite rare. It’s ἕ?δω, ἕ?δον/ ἕ?δεσκον,ἕ?ξω, ἕ?ξα and in Aesch Ag 1529 ή?ξεν, ἕο?γα, ?ώ?γειν (resent, Paratatikos, Future, Aorist, Pr. Perf, Past Perf). There are other types of the verb there
I know it doesn’t help much but I promise I’ll try more once I get some aspirins and some sleep
Since I was handily defeated in my attempts to find this verb, I was following this thread with interest. Following Irene’s post, I looked it up in the PDF LSJ, and while it had a smooth breathing, the text said this:
“this Verb took the aspirate, acc. to Schol. Ar. Ach. 329; and it is often so written in Mss”
Irene, out of curiosity, which dictionary did you use? Could you please give your dictionary title, author, and ISBN when you have the time?
Plukidi It’s Μέγα Λεξικόν της Ελληνικής Γλώσσης by Δημητ?άκος. I’ve heard it has been reprinted so the new edition will probably have an ISBN number but this one doesn’t I think
Thanks Irene. It was indeed helpful and led me to a listing in my middle Liddle of the verb καθείγνυμι, deriving from κατὰ + ἕ?γω/εἴ?γω and fitting the context quite well. Great work.
