Didacus is Latin in Origin.

Didacus is the Latinized medieval form of an Iberian given name of uncertain origin, attested in Latin charters from the 10th to 12th centuries and widely used in ecclesiastical registers. It is best known through Saint Didacus of Alcalá (d. 1463), whose canonization in 1588 spread the cult under the Latin name; the Californian city of San Diego ultimately commemorates him. In learned and liturgical contexts the Latin Didacus persisted even when the vernacular shifted.

The vernacular reflexes are Spanish Diego, Portuguese Diogo, Galician/Medieval Castilian Diago, and Catalan Dídac; rarer scholarly or Italianized forms include Didaco. Related surnames include Díaz and Dias. The etymology is debated: some derive it from Greek didachē/didaktos (“teaching, taught”), yielding a sense of “learned” or “teacher,” while others posit a pre-Roman Iberian root. Modern scholarship generally links Diego/Diogo to Didacus rather than to Santiago.
