Number pronouns can be formed by adding affixes ke- .. -nya to the collective numbers. These forms can also have a reduplicated base with or without prefix ke-.
| Kedua anak itu baik hatinya. Kedua-duanya baik hatinya. Dua-duanya baik hatinya. Keduanya baik hatinya. |
Those two boys are very kind. Both of them are very kind. Both of them are very kind. Both of them are very kind. |
Some indefinite numbers can occur as pronouns also with suffix -nya:
semuanya - all of them
segalanya - all of them
seluruhnya - all of it, the whole
Masing-masing which can occur as number pronoun does not take suffix -nya. It means ‘each of them’.
