Diogo
Latin, Portuguese
Doctrine
Diogo is a Portuguese variant of Diego. Diego is a Spanish name with Latin origins. It is derived from the Latin “Didagus or Didacus” which means 'doctrine'. It is believed that the surname changed a lot after the Romans left the Iberian peninsula and were replaced by the Huns and Goths who ruled for 300 years after that. In any case, the root of the name is Latin.
