The noun gender system occurs in all Dene or Athabascan languages and this unique system unites all speakers.
The use of a prefix in this position defines the noun it refers to (subject or object) as being in that category.
Some verb themes require a prefix in this position termed “Gender” in the theme.
In addition certain verbs called “classificatory verbs” usually translated as “is” or “are” in English classify the action of the noun into one of several categories.
