Yanomaman, also as Yanomam, Yanomáman, Yamomámi, and Yanomamana (also Shamatari, Shirianan), is a family of languages spoken by about 20,000 Yanomami people in southern Venezuela and northwestern Brazil (Roraima, Amazonas).

[4] Jolkesky (2016) notes that there are lexical similarities with the Irantxe, Taruma, Katukina-Katawixi, Puinave-Kak, Tupi, Arawa, Guahibo, and Jivaro language families due to contact.

There are five demonstratives which have to be chosen according to distance from speaker and hearer and also according to visibility, a feature shared by many native Brazilian languages such as Tupian ones including Old Tupi.

There is a distinction between alienable and inalienable possession, again a common areal feature, and a rich system of verbal classifiers, almost a hundred, they are obligatory and appear just before the verb root.

The distinction between inclusive and exclusive 1st person plural, a feature shared by most Native American languages, has been lost in Yanam and Yanomam dialects, but retained in the others.

The object of the verb can be incorporated into it, especially if it is not in focus: Non-incorporated: kamijə-ny1sg-ERGsiparaaxeja-puhi-i1sg-want-DYNkamijə-ny sipara ja-puhi-i1sg-ERG axe 1sg-want-DYN'I want an/the axe'Incorporated: kamijə-ny1sg-ERGja-sipara-puhi-i1sg-axe-want-DYNkamijə-ny ja-sipara-puhi-i1sg-ERG 1sg-axe-want-DYN'I want [it], the axe'Relative clauses are formed by adding a relativizing ('REL' below) suffix to the verb: wãro-nman-ERGshamatapirshyra-weikill-RELware-maeat-COMPLwãro-n shama shyra-wei ware-maman-ERG tapir kill-REL eat-COMPL'the man who killed the tapir ate it'Sanuma dialect also has a relative pronoun ĩ.
