Tiberius (/taɪˈbɪəriəs/ ty-BEER-ee-əs, Latin: [tɪˈbɛɾɪ.ʊs]) is a Latin praenomen, or personal name, which was used throughout Roman history. Although not especially common, it was used by both patrician and plebeian families. The feminine form is Tiberia. The name is usually abbreviated Ti., but occasionally Tib. For most of Roman history, Tiberius was about the twelfth or thirteenth most common praenomen. It was not used by most families, but was favored by several, including the great patrician houses of the Aemilii, Claudii, and Sempronii. It was probably more widespread amongst the plebeians, and it became more common in imperial times. The name survived the collapse of Roman civil institutions in the 5th and 6th centuries, and continued to be used into modern times. (en)
