Antonio Sciarretta's Toponymy
Common remarks: the place-names have been put in the nominative case, an asterisk * means not attested, reconstructed form. The late place-names of probable Latin origin have not been included. The IE roots are in the form given by Pokorny's Indogermanische Wörterbuch. The links will be active when the single pages will be published, see the main page. For any comment, suggestion, email me.
A Gaulish toponymy is also certain and well distributed especially in the Ager Gallicus, as it is obvious, but also south of it at the western borders of Picenum. This Gaulish presence is surprising but appears rather clearly from several place-names perfectly fitted by Gaulish appellatives.
