What is the Greek word for self control?

There isn't one single perfect Greek word for "self-control" that captures all its nuances. The best translation depends on the specific context. However, some strong contenders include:

* ἐγκράτεια (enkrateia): This is probably the closest single word. It literally means "self-mastery" or "continence," and encompasses the ability to control one's impulses and desires.

* σωφροσύνη (sophrosyne): This is a more nuanced term often translated as "moderation," "temperance," or "soundness of mind." It implies self-control but also wisdom, prudence, and a balanced approach to life. It's a more virtuous and holistic concept than simply restraining oneself.

The best choice between these two depends on the specific shade of meaning you want to convey. If you simply mean the ability to restrain oneself, ἐγκράτεια is better. If you want to emphasize the virtuous and balanced nature of self-control, σωφροσύνη is a more fitting choice.
