According to Peter Landerman, the Jesuits translated fragments of Christian scriptures into about 150 Indigenous languages of the Peruvian Amazon area.

There are more than 15 defined linguistic families in Peru's territory and another 15 or more languages that are isolated or not classified.

This family is formed by many local languages in the south of Colombia and in parts of Brazil.

There exists a group of languages with rare documentation and references to extinct villages, that cannot be classified due to lack of information.

(Ethnologue assigns separate language codes to more than 25 varieties of Quechua in Peru.)

The rest of the Indigenous languages of Peru have more than 105 thousand speakers in total,[10] and are located mostly in the east and north part of the country, specifically in Loreto, Madre de Dios, and Ucayali.

In northern Peru, there are 5 small families of languages: Cahuapana, Jívara, Zápara, Peba-yagua, and Bora-witoto.

These families of languages are mostly spoken in Loreto, but also in areas connected to Brazil, Colombia, and Ecuador.

In the Peruvian Amazon over forty languages, which are usually grouped into 14 families and diversifying about 120 recognizable local varieties are spoken.

While it is true that there are many foreign colonies in Peru, the majority of these abandoned their original language.

Within the first communities of immigrants lived people from Japan, China, and in smaller amounts people from Germany (central jungle in Pozuzo and Oxapampa), Italy (urban areas of Lima and Arequipa), and Arabic and Hindi (Urdu) areas.

[12] These last two are due to the recent waves of immigrants from Palestine and Pakistan (especially to the southern department of Tacna).
