I don't speak Spanish
I studied Latin in high school
Also, I speak "scoshi" Japanese, from a lifetime of studying martial arts

Knowing a bit of Latin is useful to pick up Spanish. The language is Galician, though. Latin is equally useful 😉
Latin is more about learning to read root words. When listening to romance languages, I found it easier to pick out the separate words of Italian, where French is spoken in more of a sing-song fashion
