Diego

Uncertain; “teaching” is one proposed connection.

Diego is a masculine Spanish name whose exact meaning remains uncertain. Medieval Latin records use Didacus; a possible connection with a Greek word for “teaching” is one explanation. Diego is also often linked with Santiago, but that relationship should not be treated as a proven origin. There is no single secure translation to attach to the name. In Spanish, Diego has two syllables: DIE-go, /ˈdjeɡo/. The i glides into the e, so the opening is one syllable, roughly “DYEH”. English speakers also use a three-syllable pronunciation, dee-AY-go. That difference is useful to notice if the name will be spoken in both languages. The Spanish spelling is Diego, without an accent mark. The name is used in Spain and Latin America, including Mexico and Argentina; these are places of use, not competing meanings. To the ear, the quick opening and rounded o give Diego a lively, warm finish. It can appeal to someone who likes a classic name with a relaxed sound: compact on the page, yet substantial enough to stand on its own.

Etymology: Diego belongs to the Spanish naming tradition. Its older Latin form Didacus has a disputed origin; a connection with Greek didakhē, “teaching”, is one proposal. The familiar link with Santiago is not a settled derivation.
