Domingo

Domingo is a masculine given name in Spanish- and Portuguese-speaking cultures. It derives from the Latin Dominicus, meaning “of the Lord,” and is related to Saint Dominic, founder of the Dominican Order. In addition, Domingo is the Spanish and Portuguese word for Sunday, used in calendars and liturgical contexts. That usage traces to the Latin Dies Dominicus, meaning “the Lord’s Day.”

As a given name, Domingo has been widely used in Hispanic countries. Notable individuals include Plácido Domingo, the Spanish operatic tenor and conductor, and Domingo Faustino Sarmiento, an Argentine reformer, writer, and president who shaped 19th-century education policy. The name continues to be common in the Spanish- and Portuguese-speaking world and is often used in combination with other given names.

Domingo also appears as a surname in Spanish- and Portuguese-speaking regions. Like other given names that became surnames, it can form part of a family name or patronymic lineage.

In modern usage, Domingo functions both as a personal name and as the term for Sunday in Spanish and Portuguese, reflecting linguistic and cultural ties across the broader Romance-speaking world.
