Antoninus is a proper noun that has historical roots and can be found in ancient Roman history and Latin literature. It refers to a family name that was held by several individuals in the ancient Roman Empire.
Antoninus derives from the Latin name "Antonius," which was a common Roman nomen or family name during the period. The name itself has uncertain origins but is believed to have Etruscan roots.

Outside of the context of Roman history, Antoninus may also be used as a given name, albeit in a less common manner, particularly in regions influenced by Roman culture or with connections to Latin literature.
In summary, Antoninus is a historical Roman family name that primarily refers to individuals who held the title of Roman Emperor during the Antonine dynasty. Its widespread usage in the ancient Roman Empire and its association with influential figures in history have solidified its place in the annals of both Roman and world history.
The word "Antoninus" is derived from the Roman gentilicium (family name) "Antonius". It was originally a Roman nomen (clan name) that dates back to ancient times. The name "Antonius" is believed to have originated from the Latin root "ante", meaning "before" or "predecessor". The name gained significant popularity due to its association with the Roman triumvir Marcus Antonius (Mark Antony), who was a prominent figure during the late Roman Republic era. As a result, it was frequently adopted by subsequent Roman emperors, including Antoninus Pius, who ruled in the 2nd century AD. Over time, the name "Antoninus" evolved to become a cognomen (additional name) used by various individuals in the Roman Empire.
