When did the Spanish language come into the world?

Answer 1

There is no set date. Spanish evolved from Latin, the Roman language spoken in the Iberian peninsula for hundreds of years after the Roman Empire conquered the area, until the Empire collpsed in the 5th century AD. Isolation and the influence of various "barbarian" tribes led to local dialects. In the 8th centure, the Moors invaded the peninsula, and remained in control there until the 15th century. The resultant language was heavily influenced by Arabic.

Spanish as we know it was pretty much in place by the 15th century, although it has evolved with the times, as has English and the other major languages.
