Variations of Vocabulary in the Dictionary

Question

I'm sure I've simply not come across where it says, but what do each of the abbreviations and such mean in the dictionary? I mean, I understand "Estados Unidos" and "Am", but RP? CSur? Is there simply a page I've missed in my searching? Or, can you explain them all?

Answer 1

Am= maybe America, as in the entire continent? Honestly I don't know. Rp= Don't know, sorry! CSur= I'm thinking this one is like central/southern cone, or just Southern cone.

I hope this kind of helps, although someone else might know. The problem is that each dictionary does this differently, so it's anyone's guess.
