Language contact
Jolkesky (2016) notes that there are lexical similarities with the Nambikwaran languages due to contact.[4]
An automated computational analysis (ASJP 4) by Müller et al. (2013)[5] found lexical similarities between Itonama and Movima, likely due to contact.
The postalveolar affricates /tʃtʃʼ/ have alveolar allophones [tstsʼ]. Variation occurs between speakers, and even within the speech of a single person.
The semivowel /w/ is realized as a bilabial fricative[β] when preceded and followed by identical vowels.[6]
Morphology
Itonama is a polysynthetic, head-marking, verb-initial language with an accusative alignment system along with an inverse subsystem in independent clauses, and straightforward 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).[7]
