If you already have your mission call you may have heard about the unusual Spanish that they speak in Argentina. It's no exaggeration, they really do speak a very different type of Spanish, but it is really quite beautiful in some parts of Argentina. This Spanish is referred to as "Castellano" or Castillian Spanish. It's supposed to more pure (it's really not, they just like to say it is). But this graphic down below sums up the Argentine attitude toward they language pretty well. It says "I don't speak Spanish, I speak Castellano!"
