NAMES OF PERSONS

Thus in Mārcus Tullius Cicerō we have—

1. Mārcus, the praenōmen , like our Christian or given name;
2. Tullius , the nōmen , properly an adjective denoting of the Tullian gēns (or house) whose original head was a real or supposed Tullus;
3. Cicerō, the cōgnōmen , or family name, often in origin a nickname,—in this case from cicer, a vetch, or small pea.

[*] Note.--When two persons of the same family are mentioned together, the cōgnōmen is usually put in the plural: as, Pūblius et Servius Sullae .

[*] a. A fourth or fifth name was sometimes given as a mark of honor or distinction, or to show adoption from another gēns.

Thus the complete name of Scipio the Younger was Pūblius Cornēlius Scīpiō Āfricānus Aemiliānus : Āfricānus , from his exploits in Africa; Aemiliānus , as adopted from the Æmilian gēns. ¹

[*] Note.--The Romans of the classical period had no separate name for these additions, but later grammarians invented the word āgnōmen to express them.

[*] b. Women had commonly in classical times no personal names, but were known only by the nōmen of their gēns.

Thus, the wife of Cicero was Terentia , and his daughter Tullia . A second daughter would have been called Tullia secunda or minor, a third daughter, Tullia tertia , and so on.

[*] c. The commonest prænomens are thus abbreviated:—

[*] Note.--In the abbreviations C. and Cn., the initial character has the value or G (§ 1. a).
