Peruvian Spanish can be relatively easy for foreigners to understand, as locals are known for speaking slowly and clearly. Due to varying indigenous influences, there are 4 main Peruvian dialects, chief among them being limeƱo. Still, there are many trends to be observed. Firstly, Peruvians use the same "s" sound for letters "c," "s," and "z." In addition, for "nosotros," the verb ending "maos" is observed, as opposed to "mos." Peruvians have a very interesting tendency to use a gerund to also imply a form of the past. The quintessential Peruvian phrase is "Asu Mare," which is an expression of surprise. "Soroche" is a kind of mountain sickness that tourists familiarize themselves with while seeing Macchu Picchu. "Chamba" is another common word that simply means "work".
