What Does the Name Jacir Mean?
Jacir is a masculine given name used mainly in Brazil. It is usually explained as a form of Jaci, a name from the Tupi language of Brazil's indigenous peoples, in which îasy (also written jasy) means "moon." The final -r sets Jacir apart from the shorter Jaci and from the feminine Jacira, but the exact route from one form to another is not documented, so the connection to Jaci is the customary explanation rather than a fully traced etymology.
Jacir Name History & Origins
Names drawn from Tupi-Guarani languages have been used in Brazil since the colonial period, and they became more prominent in the nineteenth century, when Romantic writers such as José de Alencar gave indigenous names to characters in novels like Iracema (1865) and Ubirajara (1874). In Tupi-Guarani tradition, Jaci - also written Îasy or Jasy - is the moon, often described in myth as the counterpart of Guaraci, the sun. The element survives in Brazilian place names, including the municipality of Jaci in São Paulo state and Jaciara in Mato Grosso. Jacir belongs to this same stream of naming rather than to the biblical or European names that begin with J; it remains uncommon and is found chiefly in Brazil. The name should not be confused with the unrelated Hebrew Jair, which has a different origin and meaning.
