Murui Huitoto is an indigenous American Huitoto language of the Witotoan family. Murui is spoken by about 1,100 Murui people along the banks of the Putumayo, Cara-Paraná and Igara-Paraná rivers in Colombia. In Peru it spoken in the North alongside the Ampiyacu and Napo rivers by some 1,000 people. Some Murui speakers live also outside their territories, for instance the vicinity of Leticia, Amazonas, Colombia. Approximately 1,000 Peruvians use Murui in both its written and oral forms. The language is accorded official status and is used in schools. It is also used in churches. There are no Murui-an monolinguals in Peru: speakers of the language who do not also use another language. The language has 1,900 speakers in southwestern Colombia where it has higher social utility and standing. It was formerly spoken in Brazil, but is now extinct in that country. Murui uses the Roman Script. There is a dictionary of the Murui language compiled by an SIL linguist, Shirley Burtch, and number of works concerning its grammar. Currently, a PhD student at James Cook University, Katarzyna Wojtylak is working on a comprehensive grammar of Murui to be published in 2017.
Phonology
Murui has a relatively small inventory of 16 contrastive consonantal phonemes some of which have restricted phonotactics. Murui consonant inventory is similar to two other dialects of Witoto, Mɨka and Mɨnɨka. The vowel inventory of the language is based on a six vowel system that consist of, among other sounds, the high central vowel ɨ. This trait is typical for languages from Northwest Amazonia, such as Tucanoan and Carib languages.
Murui is highly synthetic, predominantly suffixing and nominative-accusative. The language is predominantly verb-final; the organization of the constituents in the clause is usually SV/AOV. Grammatical relations are expressed through pronouns cross-referencing on the verb. Syntactic functions can be expressed through case markers. Marking of core arguments is generally optional and is related to focus; marking of peripheral arguments on an NP is usually mandatory. Murui has three open lexical classes. Closed classes of words are underived adjectives and quantifiers, adverbs, pronouns, demonstratives, anaphoric forms, interrogative words, low and lexicalized number words, connectives, adpositions, interjections and onomatopoeic forms. The majority of the word classes can occupy the predicate slot but there are restrictions as to what kind of sets of suffixes can be attached to non-verbs. Quantifiers, connectives, adpositions, interjections and onomatopoeic forms cannot function predicatively. One of the most salient characteristics of the nominal morphology of Murui is a large multiple classifier system that consists of at least 80 classifiers. The same classifier form can be used in a variety of morphosyntactic contexts. The system is semi-open due to the occurrence of repeaters. All types of classifiers are bound suffixes that can be either mono- or disyllabic.
Orthography
Throughout the years, the existing phonological analyses of the language have come to reflect different spelling variations with various graphemes used to describe the Witoto sounds. The first to analyze and describe the sound system of Witoto Mɨnɨka was Minor Eugene. This description was fundamental to the development of the language orthography. Nowadays, there is a tendency to use the graphemes introduced by Petersen de Piñeros. Wojtylak uses slightly modified spellings.
