Forms

cognōmentum n (genitive cognōmentī); second declension[1]

Etymology

The OLD, the TLL and Wiktionary take it as from Latin cognōscō (“to get to know”) + -mentum.[2][3][1] Lewis & Short treat it as a by-form of cognōmen (“surname”), and de Vaan lists both among the compounds of nōmen (“name”), noting that their ⟨g⟩ was taken from cognōscō.[4][5] Isidore of Seville explains it as a name added to the personal name for the sake of recognition, or as one that goes with the name.[3][6]

Earliest recorded meaning

Plautus has it first, in the Persa, of the cognomen of the stubborn Capitones.[2][5][7]

Semantic evolution

It is a surname or cognomen, and also a nickname, as Gellius tells of a Diodorus who was called Cronus.[2] Varro uses it of a cult title of Liber, and Tacitus of the name of a people.[2] Tacitus also uses it of a derived name, as he reports that the Idaei were called Iudaei by a barbarous lengthening, and simply of a name, as the Waal is the name the neighbouring peoples give one branch of the Rhine.[2] Lewis & Short note that it is rare in classical prose, absent from Cicero and most frequent in Tacitus.[4] In medieval texts it means the same as cognōmen.[8]
