* Απόφαση (Apofasi): This translates most directly to "decision," but implies the firm resolve to carry out that decision, so it can often function as "determination."
* Επιμονή (Epimoni): This means "persistence" or "perseverance," which are key aspects of determination.
* Πείσμα (Peisma): This translates to "stubbornness" or "obstinacy." While negative in some contexts, it can also describe a strong, unwavering determination, even if it's not always the most positive kind.
* Θάρρος (Tharros): This means "courage" or "bravery," which are often closely linked to determination.
Therefore, the best Greek word for "determination" depends on the context. If you can provide the context, a more precise translation can be given.
