culture changes mostly...spanish differenciates like the mexicans, puerto ricans, cubans, and south americans all speak the same spanish but have the different dialects.. thats the same with my african half I can speak arabic but at the same time I speak a jumble up arabic that is somalian that other arabs might not understand unless they speak somali..for instants if I went to spain speaking "cubano" spanish different words might not mean the same thing as they are in cuba...
hope that helps
