Vowels

The vowel system of Matses is peculiar in that no vowels are rounded. Both of its back vowels should accurately be represented as [ɯ] and [ɤ] but the convention is to transcribe them with and .(Fleck 2003, p. 72)

	Front Front vowel A front vowel is a type of vowel sound used in some spoken languages. The defining characteristic of a front vowel is that the tongue is positioned as far in front as possible in the mouth without creating a constriction that would be classified as a consonant. Front vowels are sometimes also...	Central Central vowel A central vowel is a type of vowel sound used in some spoken languages.

Consonants

The consonants of Matsés according to Fleck (2003).

Consonants	Labial Labial consonant Labial consonants are consonants in which one or both lips are the active articulator. This precludes linguolabials, in which the tip of the tongue reaches for the posterior side of the upper lip and which are considered coronals...	Alveolar Alveolar consonant Alveolar consonants are articulated with the tongue against or close to the superior alveolar ridge, which is called that because it contains the alveoli of the superior teeth...	Retroflex Retroflex consonant A retroflex consonant is a coronal consonant where the tongue has a flat, concave, or even curled shape, and is articulated between the alveolar ridge and the hard palate. They are sometimes referred to as cerebral consonants, especially in Indology...	Palatal Palatal consonant Palatal consonants are consonants articulated with the body of the tongue raised against the hard palate...	Velar Velar consonant Velars are consonants articulated with the back part of the tongue against the soft palate, the back part of the roof of the mouth, known also as the velum)....	Glottal Glottal consonant Glottal consonants, also called laryngeal consonants, are consonants articulated with the glottis. Many phoneticians consider them, or at least the so-called fricative, to be transitional states of the glottis without a point of articulation as other consonants have; in fact, some do not consider...

Grammar

The Matsés language is primarily suffixing and highly synthetic

Polysynthetic language

In linguistic typology, polysynthetic languages are highly synthetic languages, i.e., languages in which words are composed of many morphemes. Whereas isolating languages have a low morpheme-to-word ratio, polysynthetic languages have extremely high morpheme-to-word ratios.Not all languages can be...
