Because of regionalisms, I think it's not just Spain vs Latin America, every country here in Latin America has its own variations, for example the Argentina "vos" vs the México "tú", and all of the differences between the meaning of the same word like when we say "te vuelas" in Mexico, we mean like you're happy for something and acting hyper because of it, but in chile they would think you're telling them they're on drugs D: xD
