Pirahã Language — Wikipedia Summary

Pirahã (also spelled Pirahá, Pirahán), or Múra-Pirahã, is the indigenous language of the Pirahã people of Amazonas, Brazil. The Pirahã live along the Maici River, a tributary of the Amazon River.

Pirahã is the only surviving dialect of the Mura language. It is estimated to have between 250 and 380 speakers. It is not in immediate danger of extinction, as its use is vigorous and the Pirahã community is mostly monolingual.

The Pirahã language is the subject of various controversial claims: for example, that it provides evidence against linguistic relativity. The controversy is compounded by the difficulty of learning the language.

Phonology

One of the phonologically simplest languages known, comparable to Rotokas. As few as ten phonemes (or nine for women). At least two phonemic tones. Can be whistled, hummed, or encoded in music.

Syntax

Basic personal pronouns: ti (I/we), gi/gixai (you), hi (they/this). Agglutinative with many affixes. Suffixes communicate evidentiality (observed, deduced, hearsay). Verbal aspects include perfective vs. imperfective, telic vs. atelic, continuing, repeated, commencing.

Embedding and Recursion

Everett originally claimed Pirahã allows limited embedding via -sai suffix, but later reinterpreted even this as parataxis. He now states Pirahã does not admit any embedding at all. Cannot say “John’s brother’s house” but must say “John has a brother. This brother has a house.” No number-words for counting. No recursive adjective-lists. No recursive possessives.

The Everett-Chomsky Controversy

Everett’s claim that Pirahã lacks recursion challenges Chomsky’s universal grammar, which posits recursion as a core feature of all human languages. Chomsky replies recursion is an innate cognitive capacity that may or may not manifest in any particular language.

Other Features

No abstract color words (only light/dark — disputed). Personal pronouns apparently borrowed from Nheengatu. One very rare sound: [ɺ͡ɺ̼] — a lateral alveolar-labiolingual double flap.
