Ottavious is Latin in Origin.

Ottavious is a modern elaboration of the Latin Octavius, influenced by the Italian Ottavio. Octavius derives from octavus, “eighth,” a name once given to an eighth-born child or one born in the eighth month. In ancient Rome it was a prominent family name (gens Octavia); its best-known bearer is Gaius Octavius, later Emperor Augustus. The form Ottavious is rare and chiefly found in contemporary English-speaking contexts, especially in the United States from the late 20th century onward, where creative -ious endings have produced distinctive variants of classical names.

Related forms and cognates include Octavius and Octavian (English/Latin), Ottavio and Ottaviano (Italian), Octavio and Otávio (Spanish/Portuguese), and the feminine Octavia and Ottavia. Short forms such as Tavi, Tav, and Otti are common nicknames. The core meaning across all variants remains “the eighth,” carrying connotations of renewal, order, and new beginnings.
