What does agnomen mean?
An agnomen is an additional name conferred on a person, most famously in ancient Rome, where it was appended to a citizen's existing trio of names to commemorate an extraordinary accomplishment. A Roman general who conquered a foreign land might receive an agnomen drawn from that victory — Publius Cornelius Scipio, for instance, became known as Africanus after defeating Carthage in Africa. Unlike the cognomen, which identified a family branch within a clan and passed down through generations, the agnomen was a personal honor marking individual merit. In broader modern usage, the word can describe any distinguishing nickname or descriptive title attached to someone, though this sense remains relatively rare. The term carries a formal, scholarly tone and appears mainly in classical history, biography, and literary discussion. It offers writers and historians a precise vocabulary for the practice of naming that commemorates achievement.

- An honorary additional name bestowed on a Roman citizen, usually in recognition of a great deed such as a military conquest.

"After his decisive campaign in North Africa, Scipio was granted the agnomen Africanus."
"The Senate voted to award the victorious general the agnomen Germanicus."
"Writers have long delighted in giving their characters an apt agnomen — a byname that captures their essence in a single word."
The plural follows the Latin form and is standard in scholarly writing about Roman naming conventions.
"Several members of the Cornelii family bore agnomina honoring their military exploits."
In ancient Rome, winning a war could literally change your name — conquer Carthage and you might carry the agnomen Africanus for life.

Etymology of agnomen
Agnomen comes directly from Latin, formed from the prefix ad- ('to' or 'added') combined with nomen ('name'), literally meaning 'a name added on.' The Romans used it for the honorary fourth name granted to individuals for great deeds, as in Africanus or Germanicus. It entered English usage in the early seventeenth century through learned and classical scholarship. It shares its root nomen with words such as cognomen, nominate, and denomination.
