coganomes :)
Originally, long ago, a cognomen was a name given you after you had earned it to be a new last name. Nowadays, cognomen as often means a nickname, or something you're called that references who you are. For example, one of my cognoma is "Crimbones". Everyone I know will understand who that refers to.
A Roman last name was his/her cognomen. The Romans usually had three names, the praenomen, nomen and cognomen. Praenomen was their given name, such as Gaius or Marcus; the nomen was their gens or clan name, such as Julius or Claudius; and the cognomen was the name of the branch of the clan to which the person belonged.
A cognomen is the third name in the Roman naming convention, typically used to distinguish individuals within a family or clan. It followed the praenomen (given name) and nomen (family name) and often indicated a person's branch of the family or specific characteristics. In modern usage, "cognomen" can refer to any surname or nickname that signifies personal identity.
