Possessive morphology differs depending on the lexical class of the possessed noun. For example, Noun Class A will take Possessive Affix A while Noun Class B will take Possessive Affix B. 

<br><br>An example comes from Nez Perce, which has three noun classes: two for kinship terms and one for other nouns. The NP <i><b>na'–</b>tóot</i> '<b>1sg-</b>father' for 'My father' illustrates the first kinship possessive class, and the NP <i><b>'in'm-</b>é:ks</i> '<b>1sg-</b>man's.sister' for 'My sister' illustrates the second kinship possessive class. Finally, the NP <i><b>'íi-</b>nim titóoqan</i> '<b>1sg-GEN</b>.people' for 'My people' illustrates the form for the rest (Nichols & Bickel 2008).
