Which language community in Peru does not give proper names to their members?

Answer 1

I do not know of a Peruvian group that matches this description. Interestingly, though, the Huichol people of Mexico do not tell strangers their correct names; they fear strangers would use their names to open them up to sorcery, which they believe would endanger their crops, health and even lives. Instead, they give false names to people they don't know, including visitors such as medical personnel and census takers.

Answer 2

The Yanomami community in Peru does not traditionally assign proper names to their members. Instead, they are often referred to in descriptive terms based on physical features or other characteristics.
