Itonama is a moribund language isolate

Language isolate

A language isolate, in the absolute sense, is a natural language with no demonstrable genealogical relationship with other languages; that is, one that has not been demonstrated to descend from an ancestor common with any other language. They are in effect language families consisting of a single...

. Greenberg’s (1987) classification of Itonama as Paezan, a sub-branch of Macro-Chibchan, remains unsupported and Itonama continues to be considered an isolate or unclassified language.

Vowels

	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. The defining characteristic of a central vowel is that the tongue is positioned halfway between a front vowel and a back vowel...	Back Back vowel A back vowel is a type of vowel sound used in spoken languages. The defining characteristic of a back vowel is that the tongue is positioned as far back as possible in the mouth without creating a constriction that would be classified as a consonant. Back vowels are sometimes also called dark...

A diphthong , also known as a gliding vowel, refers to two adjacent vowel sounds occurring within the same syllable. Technically, a diphthong is a vowel with two different targets: That is, the tongue moves during the pronunciation of the vowel...

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:...	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...	Postalveolar Postalveolar consonant Postalveolar consonants are consonants articulated with the tongue near or touching the back of the alveolar ridge, further back in the mouth than the alveolar consonants, which are at the ridge itself, but not as far back as the hard palate...	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...
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 &...	Plain	p	t		tʲ	k	ʔ

Fricative Fricative consonant Fricatives are consonants produced by forcing air through a narrow channel made by placing two articulators close together.

Lateral Lateral consonant A lateral is an el-like consonant, in which airstream proceeds along the sides of the tongue, but is blocked by the tongue from going through the middle of the mouth....			l
Flap Flap consonant In phonetics, a flap or tap is a type of consonantal sound, which is produced with a single contraction of the muscles so that one articulator is thrown against another.-Contrast with stops and trills:...			ɾ
Semivowel Semivowel In phonetics and phonology, a semivowel is a sound, such as English or , that is phonetically similar to a vowel sound but functions as the syllable boundary rather than as the nucleus of a syllable.-Classification:...		w			j

The postalveolar affricates /tʃ tʃʼ/ have alveolar allophones [ts tsʼ]. Variation occurs between speakers, and even within the speech of a single person.

The semivowel /w/ is realized as a bilabial fricative

Morphology

Itonama is a polysynthetic, head-marking, verb-initial language with an accusative alignment system along with an inverse subsystem in independent clauses, and straight-forward accusative alignment in dependent clauses.

Nominal morphology lacks case declension and adpositions and so is simpler than verbal morphology (which has body-part and location incorporation, directionals, evidentials, verbal classifiers, among others).
