La Fregeneda, whose name is a group of ash trees (lat. fraxinus) and this is a tree with a notable presence in the toponymy around La Raya. The Salamancan toponym, which reminds us of Fregenal de la Sierra in Badajoz due to the Leonese influence in its result, is very close to the Portuguese Freixo de Espada à Cinta, while in the lands of Miranda we find Freixenosa -port. Freixiosa-. There was also Casais de Freixeira, on the Portuguese side of the Raya, opposite Villanueva del Fresno, to the south of Badajoz.
