I am currently in the process of translating a text from one language into another, and the original uses a compound noun that can either be translated into English as "fly-eating" (losing the original's charm) or a fancy quasi-medical term involving "-phagia". I have tried searching for rules regarding Ancient Greek compound nouns' formation but could not unearth a definite algorithm.
The word for "fly" would be myia and -phagia could be appended at the end to signify "eating". I would appreciate it if someone with better knowledge of Ancient Greek could help me combine the two together, and I would love to see some scholarly articles on this topic. Surely there are some rules that medical scientists and jurisprudents follow when giving names to new terms?
