The surname Parti has an anthroponymic and nickname origin with several possible interpretations. In this sense, F. De Laurentiis notes that it may derive from the name Parthi, in turn originating in a byname related to Parthia, that is, the people of the Parthians, which would indicate an ethnic or cultural reference.

On the other hand, both F. De Laurentiis and E. Rossoni agree that, in many cases, the surname may derive from nicknames formed from the term parti, in the sense of “division,” “part” or even specific social roles. In this way the surname could reflect both an ethnic reference and a descriptive designation linked to functions or characteristics within the community.
