Notes

Notes: Sebang expresses relative seniority, not merely adulthood or being generally old. In a family context it denotes the eldest or senior child/sibling relative to the others.

Editorial caution: Keep this distinct from sebangan “east.” The formal resemblance alone is insufficient evidence that the directional term derives from the kinship word.
