Is "epicharia" or "epikaria" a Greek word?

Question

I recently requested a word from Greek which means, "knowing when to break the rules". The question I asked generated a lot of fine responses, but unfortunately it could not remind me of the original word that I had heard from my friend.

Even more recently, I asked my friend which word he had used, and he replied with epikaria or epicharia. However, we are both having a hard time finding this word in any dictionary. It does, interestingly enough, show up on Google searches.

Does Greek have the word epikaria or epicharia?

Answer 1

Could the word have been ἐπίκαιρα (epícaera)?

This is the neuter plural of the adjective ἐπίκαιρος (epícaerus, second declension two-termination). It could also potentially be an adverbial form, though I'd expect ἐπίκαιρον instead for that.

This adjective means either "at just the right time", "for only a certain time", or in medicine, "very serious". It comes from the noun καιρός meaning "the right time", suggested in a (now sadly deleted) answer to the other question.

This is the closest word I can think of which pertains to timing.

Answer 2

Short answer: No :) I'm a native Greek speaker with some knowledge of ancient Greek and neither epicharia nor epikaria rings a bell, while Google doesn't return anything that can lead to associations. (Epicharia seems to be the name of a saint, but its form can easily be recognized as, precisely, a constructed name.)

Answer 3

Another similar-sounding word with similar meaning: ἐπιορκία (pr. epiorkia). Oathbreaking, false swearing.
