What is the Greek word for fearless?

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

* ἀτρεκής (atrekēs): This word implies unwavering, steadfast, and resolute, often in the face of danger. It suggests a lack of fear stemming from courage and determination.

* ἀνδρεῖος (andreios): This means "manly," "brave," or "courageous." While not directly "fearless," it strongly implies a lack of fear, particularly in the context of battle or facing danger.

* θαρραλέος (tharraléos): This word signifies "bold," "courageous," or "confident." It suggests a spirit undeterred by fear.

The most appropriate word would depend on the situation and the type of fearlessness being described. For example, `atrekēs` might be better for someone facing a difficult task, while `andreios` might be more suitable for a warrior.
