-> What Happens When a Language Has No Numbers?
The Pirahã are an indigenous people, numbering around 700, living along the banks of the Maici River in the jungle of northwest Brazil. Their language, also called Pirahã, is so unusual in so many ways that it was profiled in 2007 in a 12,000-word piece in the New Yorker by John Colapinto, who wrote:

Unrelated to any other extant tongue, and based on just eight consonants and three vowels, Pirahã has one of the simplest sound systems known. Yet it possesses such a complex array of tones, stresses, and syllable lengths that its speakers can dispense with their vowels and consonants altogether and sing, hum, or whistle conversations.
