* χάρισμα (chárisma): This word implies a gift or grace, often a natural talent bestowed by the gods. It's a good choice if you're referring to an innate ability.
* τάλαντον (tálanto): This word originally referred to a unit of weight or currency, but it can also metaphorically mean a "talent" or "ability," especially a significant one. However, this is less common in the sense of natural aptitude.
* δεξιότητα (dexiótita): This word means skill or dexterity, implying proficiency acquired through practice. It's suitable if the "talent" is more about learned ability than innate gift.
* ικανότητα (ikanótita): This translates to ability or capacity, a more general term encompassing talent.
The best word to use will depend heavily on the specific nuance you want to convey.
