Toponymy
The word Illán derives from the Latin Iulianus. The town's name stems from the worship of San Illán or San Julián ("Saint Julian"). The word de simply means "of". The last word, Vacas, despite its current meaning in Spanish – namely "cows" – apparently has an Arabic origin, deriving from a word Wakka. In a document from the latter half of the 16th century, it says that the town's name is "Vacas", and that a fortunate man named Illán lived there.
