The name
Nazaire is the French form of the Latin name Nazareus, from the Ancient Greek name Nazarios. It means "from Nazareth". In Italian and Spanish it is
Nazario, in Catalan is Nazari, in Romanian Nazarie.
Saint-Tropez, as a toponym, seems to be an archaic deformation of the name of a Saint called "
Caius Silvius Torpetius". Other forms of this name (in Latin, French and Italian) are Torpetius, Tropesius, Torpès, Tropez, Torpete, Torpè, Torpes, Torpezio, Tropezio. It's not uncommon for a toponym to have an ancient, regional, deformed, alternative, mistaken name of a Saint. There is an
Abbey in Füssen dedicated to "Saint Mang" (Saint
Magnus). Sankt Pölten, a city in Austria, is derived from Saint Hippolytus. "San Rossore" (literally "Saint Blush"), a place in Italy, is in reality dedicated to San Lussorio (Saint Luxorius).
