Annius as a Baby Name. Meaning and Origin of Annius

What is the meaning of the name Annius ?

The baby name Annius is a Male name , 3 syllables long and is pronounced {'classical_latin': '/ˈan.ni.us/', 'anglicized': '/ˈæn.i.əs/'}.

Annius is Latin in Origin.

Annius is a Latin masculine name, originally the Roman nomen (family name) of the plebeian gens Annia. The etymology is debated: it may connect with Latin annus “year,” or reflect a non‑Latin Italic/Etruscan root. In antiquity Annius marked clan affiliation rather than serving as a personal praenomen.

The name is well attested in the Republic and Empire, borne by figures such as Titus Annius Milo and Marcus Annius Verus (the birth name of Emperor Marcus Aurelius). In modern usage Annius is a rare classical‑revival given name. Variants and related forms include the feminine Annia, the derivative Annianus/Anianus, and Italian learned Annio. Meaning is best taken as “of the Annian clan,” with a possible “yearly” nuance if the annus link is accepted; avoid confusion with Greek Anius.
