A last hypothesis aims that the name "Zarza" can be related to the group of place names derived from the Latin "quercus" "oak", as Cerceda, Cercedilla, Cercedo, etc. Since "quercus" is a feminine name of fourth decline in Latin, bramble might derive from the form of the Latin "quercea", "oak". Another possibility is that from the adjective "querceus", "relative to the oak", there comes the form of neutral plural *quercea, "place abundant in oaks, grove of evergreen oaks". The evolution would be "Quercea> *Kercea> *Kercia> *Cerza> Zarza". Other points in favour of this hypothesis are the thick groves of evergreen oaks preserved in the surroundings of the municipality.
