* Συνάντηση (synántēsi): This is probably the closest general equivalent and means "meeting" in the sense of an encounter or appointment. It's widely used and suitable for most contexts.
* Σύσκεψη (sýskesi): This refers more specifically to a formal meeting, often a business meeting or a council.
* Συνεδρίαση (syneríasi): This word implies a session or sitting, often of a formal body like a parliament or committee.
* Συνέλευση (synéleusi): This means assembly or gathering, often a large and more informal gathering.
So, the best word to use depends on the context. For a casual meeting with friends, Συνάντηση (synántēsi) is fine. For a board meeting, Σύσκεψη (sýskesi) or Συνεδρίαση (syneríasi) would be more appropriate.
