What's the difference between Spanish style interiors and Mexican style interiors?

I sometimes mix them up, because they look quite the same to me, so I would like to know what's the main difference between these two styles. And also, what makes the Spanish style interiors different from Mediterranean, Moorish, Tuscan and other similar styles. Thank you for your help!

Why do people from Spain who speak Spanish, speak a different style and with a lisp?

As opposed to Hispanic-American Spanish speaking people. I am fluent in Spanish but don't have the Spanish style or lisp either.

Speak spanish??

what is the spanish translation of this phrase??

its transition into the modern spanish style of the sport

Thankyou
