The surname Offredi is of anthroponymic origin and derives from personal names of Germanic root. On this point E. Rossoni and Surnames in Italy agree, linking it with forms such as Offredo or with variants obtained by aphaeresis from names such as Goffredo, Loffredo or Roffredo, all belonging to the same onomastic family.

From the etymological point of view, Surnames in Italy relates it with Germanic compounds such as Otfrid or Godefrid, whose elements point back to concepts such as "wealth", "peace" or "divine protection". Along the same lines, E. Rossoni confirms this origin and highlights the phonetic processes that gave rise to the different forms, reflecting the evolution of the personal name in its fixing as a hereditary surname.
