Augusto

A masculine Spanish, Italian, and Portuguese given name from Latin Augustus, an ancient honorific conveying reverence, sacred standing, and dignity.

Last updated: 2026-08-05

Augusto is a masculine given name used in Spanish, Italian, and Portuguese. It is the Romance-language form of Latin Augustus. The most defensible short meaning is “venerable” or “worthy of honour”; “sacred,” “majestic,” and “dignified” describe other parts of the Latin word’s range. It is misleading to reduce the name to the modern promise “one who will become great.”

From Latin Augustus to Augusto

The *Oxford Dictionary of First Names* treats Augusto as the Italian, Spanish, and Portuguese cognate of Augustus. In each language, Augusto is an established full given name, not merely a nickname for Augustus.

Latin augustus was an adjective before and alongside its use as a personal designation. The *Oxford Latin Dictionary* entry, reproduced with its senses and citation details, gives “solemn” or “venerable” in religious use, “worthy of honour” for a person, and “majestic” or “dignified” more broadly. The Royal Spanish Academy similarly defines Spanish augusto as inspiring or deserving great respect and veneration because of majesty and excellence.

Those definitions explain the name’s honorific character. They do not mean that Augusto literally denotes an emperor, a nobleman, or a person with a majestic personality.

The Deeper Etymology Is Not a Simple Translation

Older summaries often connect Augustus directly with Latin augere, “to increase,” and turn that connection into the name meaning “the increaser.” That is too neat. Treccani connects augustus with augur and explains its original religious sense as “consecrated by the augurs,” hence “venerable.”

The relationship with augere remains important, but its oldest nuance is debated. In a review of interpretations by Bréal, Meillet, and Benveniste, linguist Odon Vallet notes agreement about the word family but disagreement over whether the underlying idea was ordinary increase, creation, or a supernatural power that causes something to come into existence. For a name entry, “venerable,” “sacred,” or “worthy of honour” therefore reflects the attested Latin senses more reliably than a speculative one-word formula such as “increase.”

Why the Roman Title Matters

In 27 BCE, the Roman Senate conferred Augustus on Octavian. In section 34 of his *Res Gestae*, Augustus himself says that he received the title by decree of the Senate; Treccani records that it was subsequently used as a title of Roman emperors. This episode made Augustus exceptionally prominent as a name and title, but the underlying Latin adjective was not invented for Octavian.

The history also explains the name’s elevated associations without turning them into genealogy. A modern Augusto shares a linguistic name tradition with Augustus; the name alone says nothing about Roman descent, imperial ancestry, social rank, or nationality.

Spanish, Italian, and Portuguese Pronunciation

The spelling is the same in all three languages, but the sounds are not identical. The stress falls on gus:

  • Spanish: /au̯ˈɣusto/, with a softer intervocalic g than in English;
  • Italian: /au̯ˈɡusto/, with a firm g;
  • European Portuguese: /awˈɡuʃtu/;
  • Brazilian Portuguese: /awˈɡustu/ in the broad transcription used by the source.

These transcriptions follow the language-specific pronunciations documented by Behind the Name’s Augusto entry. Actual Portuguese pronunciation varies by region, so a bearer’s own pronunciation is the best guide.

Related Names—and Names That Are Not Exact Equivalents

The closest historical equivalent is Augustus, the Latin form. Augusta is the feminine counterpart recorded for Italian and Portuguese, while August, Auguste, and other European forms belong to the same broad name family.

Several familiar names are related but follow a different formation:

  • Agustín in Spanish, Agostino in Italian, and Agostinho in Portuguese descend from Latin Augustinus, a derivative of Augustus.
  • Augustine and Austin also belong to that Augustinus branch.
  • August may be a form of Augustus in several languages; in English it can also be chosen directly from the month name.

This distinction matters in historical records: Augusto and Agustín, for example, are related names, not automatic spelling variants of one another. A translated or Latinized document may use a cognate, but identity requires evidence beyond the shared root.

Is Augusto Connected with the Month of August?

Yes, indirectly. The month commemorates the emperor Augustus; Treccani’s account of the month name traces Italian agosto to Latin augustus in his honour. Augusto and the month therefore share the same Roman historical reference.

That connection does not make Augusto inherently a seasonal name. Nothing in its etymology implies that a bearer was born in August, and a particular family may have chosen it for religious, familial, literary, or purely personal reasons.

Given Name, Surname, and Genealogy

Augusto is principally a masculine given name in the languages covered here. It can appear in a family-name field, but a database position alone does not establish that it is hereditary: compound personal names, Iberian and Portuguese naming conventions, and reversed catalogue fields can all affect how a full name is displayed.

Etymology explains where the name came from; genealogy explains why a particular person bore it and how that person is related to others. Shared use of Augusto does not establish a common lineage.
