Roman Praenomia

• Appius (Ap.) only used by gens Claudia.
• Aulus (A.) or Olus.
• Caelus from Etruscan Caele.
• Decius associated with gens Minatia.
• Decimus (D.) "tenth".
• Faustus "lucky" an archaic praenomen revived by the dictator Sulla for his twin children. Used by his descendants ever after. Uncommon.
• Flavius from flavus ("golden"), imperial praenomen after the 3rd century.
• Gaius (C.) often written as "Caius", because it was originally spelled that way before C and G were separated. From Etruscan Cae or Cai, meaning unknown.
• Gnaeus (Cn.) often written as "Cnaeus".
• Kaeso (K.) or Caeso uncommon.
• Lucius (L.) common.
• Mamercus (Mam.) from Etruscan Mamerce.
• Manius (M'.) uncommon, "M'." often confused with "M."
• Marcus (M.) from Etruscan Marce, meaning unknown. There may be a connection with Mars if he turns out to be of Etruscan origin. Common.
• Mettius from Etruscan Metie.
• Numerius (N.) from Etruscan Numesie, associated with gens Fabia.
• Publius (P.) from publius ("public"), common, originally Etruscan Puplie. Latin populus is probably from the same Etruscan word, as Pupluna became Populonia in Latin.

• Septimus (Sept.) "seventh".
• Servius (S. or Ser.) from servo ("to preserve"); uncommon.
