The main language spoken here is Spanish, though many location names come from Nahuatl, the indigenous language. I haven't met anyone who speaks it, yet, but I have had a fun time trying to pronounce some of their words. For example, the volcano near my house is called Popocatépetl. The "l" at the end of the word doesn't actually make an "l" sound, though, you just put your mouth in the same position you would to say "l" and blow out air. It's really hard to get right since that sound doesn't exist in English or Spanish!
The currency here is called the peso. There are approximately 20 pesos in one dollar. An interesting fact is that the currency symbol here is the same one that we use for the US dollar, $. That led to some confusion during my first few weeks here.
Since tap water here is not potable, which means that you cannot drink it safely, everyone buys clean water to drink. When I fill a 20 liter garrafón, or jug, with water from the purifier down the street, it only costs 12 pesos, or sixty cents. However, if you buy an individual bottle of water from a convenience store, it will still cost about 10 pesos.
