The surname after “i” in Salvador Dalí’s full Catalan name is Domènech.
His full name is Salvador Domingo Felipe Jacinto Dalí i Domènech. In Catalan naming practice, “i” means “and” and connects a person’s paternal and maternal family names. Thus, Dalí is the first family name and Domènech is the second, rather than a middle name in the usual English-language sense.
Dalí was born in Figueres, Catalonia, in 1904 and retained the Catalan form of his name in biographical and artistic contexts. International publications generally shorten it to Salvador Dalí, the name under which he became famous.
The accent in Domènech is significant in the Catalan spelling. It is easy to confuse the components of his full name because several given names appear before the two family names. “Salvador” is his given name, while Dalí and Domènech are the connected surnames.
