* κλήση (klīsē): This is probably the closest single word and often translates to "calling" in the sense of a vocation, a divine summons, or a strong feeling of purpose. It's often used in religious contexts.
* φωνή (phōnē): This means "voice" or "sound," and could be used if the "calling" is a literal shout or summons.
* πρόσκληση (prós-klēsē): This translates to "invitation" or "summons," suggesting a formal call or request.
* ανάκληση (anáklesē): This means "recall" or "revocation," which could apply if the "calling" is to undo something.
To choose the best word, you need to specify what kind of "calling" you mean. For example:
* A religious calling: κλήση (klīsē)
* A phone call: τηλεφωνική κλήση (tilefonikī klīsē) – literally "telephone calling"
* A formal invitation: πρόσκληση (prós-klēsē)
Therefore, there's no single answer without more context.
