"The Spanish language reflects the legacy of Eurasian ancient civilizations, a legacy enriched through the centuries by movements of peoples and groups into and out of the Iberian Peninsula. Spanish also is reflected in geographical names on the landscapes of the New World. From the first moment Spanish conquistadors set foot on the American mainland, they left Spanish language place names on the land (toponyms)."
