Behind the Name - the Etymology and History of First NamesFrom the Spanish and Portuguese name Teresa. It was first recorded as Therasia, being borne by the Spanish wife of Saint Paulinus of Nola in the 4th century. The meaning is uncertain, but it could be derived from Greek θέρος (theros) meaning "summer", from Greek θερίζω (therizo) meaning "to harvest", or from the name of the Greek island of Therasia (the western island of Santorini).
