Ruiz

Ruiz is a Spanish patronymic surname meaning 'son of Ruy', where Ruy is a medieval short form of Rodrigo. The name ultimately traces back to the Germanic name Roderick, derived from the elements hruod ('fame') and rih ('ruler, king'), thus meaning 'famous ruler'. This etymology connects Ruiz to the Visigoths, the Germanic tribe that dominated the Iberian Peninsula from the 5th to the 8th centuries.

Etymology and History

The patronymic Ruiz is formed by adding the suffix -ez (meaning 'son of') to the given name Ruy. Comparable patterns occur in many Spanish surnames such as Rodríguez (from Rodrigo) or González (from Gonzalo). The given name Ruy is documented in medieval Portugal and Castile, famously borne by the 11th-century military commander Rodrigo Díaz de Vivar, better known as El Cid, whose nickname stemmed from the Arabic al-sayyid 'the lord'. Although El Cid's full name was Rodrigo, he was sometimes referred to as Ruy or Rui, solidifying the short form in the onomastic tradition.
