Non-personal nouns that refer to objects have a prefix of an-/am-/ang- to denote singular.
The plurals will have fan-/fam-/fang-, e.g., angkeltot = a star; fangkeltot = many stars; anman = a bird; fanman = many birds
Possession in person (family) relationships employs suffixes:
E.g.:
sikou = child;
tamri = their father;
tabung = my father(tidung = my mother);
paklum = your head;
