Definition: A sessio is a historical term that refers to a session or a sitting. It comes from the Latin word "sessio parliamenti" which means "the sitting of Parliament".

Examples:

• During the sessio parliamenti, the members of Parliament would gather to discuss and make decisions on important matters.
• The court sessio was held to hear the arguments of both parties and make a fair judgment.
