Editing Tewa language (section)

=== Grammatical number ===
Tewa, like other Tanoan languages, has a trepartite [[Grammatical number|number system]], which means that nouns can be counted through different syntactic constructions in three ways. In English, with morphosyntactic differences exist only for two numbers: singular and [[plural]]. Tewa, on the other hand differentiates between singular, [[Dual (grammatical number)|dual]], and plural nouns. 

However, Tewa also appears to group its nouns into two categories: those of "sets" and "entities", with sets being marked by the affix /-n/ and entities the lack of said affix. Because of this, when creating plurality out of an entity, the affix /-n/ must be removed and the base root will be one not seen outside of plurality or duality.

Tewa also has what is called "inverse" numbering, which is a feature of many Tanoan languages. A chart of the indefinite articles for "a, some" can help show this phenomenon: 

{| class="wikitable"
!
!Singular
!Dual
!Plural
|- align="center"
!Class I
|wí
|wên
|wên
|- align="center"
!Class II
|wên
|wên
|wí
|- align="center"
!Class III
|wí
|wên
|wí
|}

As seen, that which marks singular for one class marks plural for another class and vice versa.
