Usually the plural is expressed with tule/tle/te. There are certain cases where a plural morpheme is not required and the interpretation is still plural, e.g. if the plural is expressed through context: ma pu lja [hand PREP 3SG] 'his hand' vs. ma pu vusot [hand PREP 2PL] 'your (pl) hands' (Ehrhart 1993: 120).
