| Ibu / Mama | Mother (intimate) | |
| Anak | Child / Son / Daughter | |
| Suami | Husband | |
| Istri | Wife | |
| Kakak | Older sibling (brother/sister) | Gender-neutral; also respectful address for slightly older person |
| Adik | Younger sibling (brother/sister) | Gender-neutral; also for younger person |
| Kakek | Grandfather | |
| Nenek | Grandmother | |
| Paman | Uncle (father's/mother's brother) | |
| Bibi | Aunt (father's/mother's sister) | |
| Sepupu | Cousin | |
| Menantu | Son-in-law / Daughter-in-law | |
| Cucu | Grandchild | |
| Buyut | Great-grandparent / Great-grandchild | Reciprocal term |
| Ipar | Brother-in-law / Sister-in-law | Spouse's sibling OR sibling's spouse |

Key Cultural Notes: No separate words for "brother/sister" by gender (use kakak laki-laki/perempuan). Respect terms (Bapak/Ibu/Kakak) used universally for elders/strangers. Family = extended clan (keluarga besar).
