What Does the Name Diago Mean?

Diago is a rare spelling of the Spanish name Diego, whose Portuguese counterpart is Diogo. The customary meaning given for these names is "supplanter," the sense attached to James, the English form of the Hebrew name Ya'aqov (Jacob) as it passed through Greek Iakobos and Latin Iacobus. In the Iberian Peninsula that link runs through Santiago, "Saint James," in which Iago is an old form of James.

A second explanation derives Diego from the Latin Didacus, the name under which the fifteenth-century Spanish friar known as San Diego de Alcalá was recorded. The origin of Didacus itself is not settled; a suggested connection with Greek didachē, "teaching," is a guess rather than a demonstrated root. Which line produced Diego - and therefore Diago - is still disputed, so "supplanter" reflects the traditional identification with James rather than a certain etymology.

Diago Name History & Origins

Diago is recorded in medieval Spanish documents as one of several spellings of the name now written Diego; forms such as Diago, Diaco, and Dieco appear before the modern spelling became standard. The name is old in Iberia and is the Spanish counterpart of James, with the Portuguese equivalent Diogo.

One traditional account of how the name took shape links it to Santiago, "Saint James": the old Spanish Iago (James) is said to have been altered in everyday speech so that Sant Iago yielded both Santiago and, by a separate path, Diego. A competing account connects the name with the Latin Didacus. Because the two explanations have long been argued side by side, the early development of the name is not settled.

From Spain and Portugal the name spread to Latin America with Spanish and Portuguese settlement. In English-speaking use, Diago is uncommon and is generally met as a spelling variant of Diego.
