What is the Greek word for vengeance?

There isn't one single perfect Greek word for "vengeance," as the best translation depends on the nuance. However, some possibilities include:

* Έκδικηση (ékdikisi): This is a common and fairly direct translation, encompassing the idea of retribution or revenge.

* Τιμωρία (timoría): This translates to "punishment," but can be used in the context of vengeful punishment.

* Νεκμή (nekmē): This word implies a more intense, relentless pursuit of revenge.

The best choice would depend on the specific context.
