Answer: Spanish is a rich language that has serious culture coming from it. As a learner, I feel that it is important to learn where Spanish came from because it has deep roots and is a very interesting thing to learn. The history of Spanish didn't just originate in one place and that was it, but it has changed over time and is spoken differently in different places just like English or other languages. With it being spoken so much, it only sparks interest in learning the history. It's also important to know these things due to the ever-changing society so you want to be as informed as possible.
Hope that helped!
