The
agnomen (plural
agnomina) formed an additional part of some
Roman names. Within the full name, it was usually placed following the
cognomen. Typically an agnomen was a
nickname acquired at some point during the lifetime, but, rarely, some agnomina were inherited.
Some examples of agnomina are given in the following table.
| Agnomina | Example |
| Africanus | general Publius Cornelius Scipio Africanus |
