Roman Names: Praenomen, Nomen and Cognomen
How a Roman citizen's three-part name worked, what Gaius Julius Caesar's name tells us, and why many Roman women shared their family name.
Roman names follow a pattern that still shapes how we talk about famous Romans.
The three names
A Roman male citizen normally had three parts, the tria nōmina:
| Part | Meaning | Example |
|---|---|---|
| praenōmen | personal name | Gāius |
| nōmen | family (clan) name | Iūlius |
| cognōmen | branch or nickname | Caesar |
So Gāius Iūlius Caesar means "Gaius, of the Julian clan, of the Caesar branch".
Common praenomina
Romans used only a small stock of personal names, often abbreviated: Gāius (C.), Mārcus (M.), Lūcius (L.), Pūblius (P.), Quīntus (Q.), Tiberius (Ti.). That is why you see M. Tullius Cicero and C. Iūlius Caesar in inscriptions.
What cognomina meant
A cognomen often began as a nickname and became hereditary:
- Cicerō — from cicer, "chickpea"
- Nāsō — "big nose" (the poet Ovid's cognomen)
- Rūfus — "red-haired"
Women's names
Roman women usually had only the feminine form of the family name:
- Iūlia — a woman of the Julian clan
- Cornēlia — of the Cornelii
- Tullia — of the Tullii, Cicero's daughter
Sisters in the same family could share the name and be told apart as Māior (elder) and Minor (younger).
Freed slaves and adoption
- A freed slave took the praenomen and nomen of his former master and kept his old name as a cognomen.
- An adopted son took the adopter's name, sometimes keeping his old clan name in the form -ānus. The emperor Augustus was born Gāius Octāvius and took the name Gāius Iūlius Caesar after being adopted by Julius Caesar.
Names in English
Roman names survive in English: Julius, Augustus, Claudia, Victoria (from victōria, victory), Felix ("lucky"), Vincent (from vincēns, "conquering") and Patrick (from patricius, "of noble birth").
Reading inscriptions
Look for the three parts and the abbreviations. On tombs, D. M. stands for Dīs Mānibus, "to the spirits of the departed".
Tips
- Learn the three parts.
- Learn common abbreviations (C., M., L., P.).
- Use the dictionary to check name meanings.
