The Languages of Hydaelyn

[Gospel]

Hi, I've always been curious about just how many languages there are in the world of Hydaelyn. I'm aware that there must be quite a few but if anything, would it be possible to give us a list of the known languages and maybe even an example of how they might sound like to others?

I know an example would be with the Sylph tribe. Whenever they speak, to those that don't understand their language they would often just hear ringing and humming but to those that do, they would hear them speaking in a strange dialect where they always referred to themselves and everyone around them in third person.

I'm also very curious about Garlemald and how they go about with their way of speech. I'm well aware that they come from the north(lol) but because of how their army works, they must be a melting pot of different cultures and races that were adopted into their own. So does this mean the Garleans teach new followers their language (assuming they have one?) or do they all just speak a universal language?
