We also find instances of mixed plurals expressed by means of both stem change (including suppletion) and plural suffixes: nasaw-ín women-PL (see Example 48). Stem change is due to the borrowing of Arabic internal plurals. The use of the plural word nas 'people' is limited to collective plurals referring to animals.
