Vowels

Proto–Uto-Aztecan is reconstructed as having an unusual five-vowel system: *i *a *u *o *ɨ. Before Langacker (1970) demonstrated that the fifth vowel should be reconstructed as *ɨ as opposed to *e, there had been a long-running dispute over the proper reconstruction (Campbell 1997:136).

Consonants

	Bilabial Bilabial consonant In phonetics, a bilabial consonant is a consonant articulated with both lips. The bilabial consonants identified by the International Phonetic Alphabet are:...	Coronal Coronal consonant Coronal consonants are consonants articulated with the flexible front part of the tongue. Only the coronal consonants can be divided into apical , laminal , domed , or subapical , as well as a few rarer orientations, because only the front of the tongue has such...	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)....	Labialized velar	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...
Stop Stop consonant In phonetics, a plosive, also known as an occlusive or an oral stop, is a stop consonant in which the vocal tract is blocked so that all airflow ceases. The occlusion may be done with the tongue , lips , and &...	*p	*t		*k	*kʷ	*ʔ
Affricate Affricate consonant Affricates are consonants that begin as stops but release as a fricative rather than directly into the following vowel.- Samples :...		*ts
Fricative Fricative consonant Fricatives are consonants produced by forcing air through a narrow channel made by placing two articulators close together.

Nasal Nasal consonant A nasal consonant is a type of consonant produced with a lowered velum in the mouth, allowing air to escape freely through the nose. Examples of nasal consonants in English are and , in words such as nose and mouth.- Definition :...	*m	*n		*ŋ
Rhotic Rhotic consonant In phonetics, rhotic consonants, also called tremulants or "R-like" sounds, are liquid consonants that are traditionally represented orthographically by symbols derived from the Greek letter rho, including "R, r" from the Roman alphabet and "Р, p" from the Cyrillic alphabet...		*r
