The name Mateo: origin and meaning
Mateo is a name of Hebrew origin, meaning "Gift of God". It has travelled across Europe for centuries — its earliest bearer in the Christian tradition is Saint Matthew the Apostle and Evangelist, and in modern times it has become widely recognised through cultural figures such as Mateo Kovačić (Croatian footballer), Mateo Retegui (Italian footballer).
In Iceland, a name must also fit Icelandic grammar (it needs a genitive form) and the Icelandic alphabet. The cultural reference to Saint Matthew the Apostle and Evangelist is respected but not sufficient on its own.
