ambilineal
Relating to a system of descent in which individuals may choose to affiliate with either their father's or their mother's line.
Unlike bilateral descent (which automatically tracks both sides), ambilineal descent forces or allows a choice, usually based on which side offers more land, status, or resources.

Example sentences
- "Ambilineal descent systems are common in Polynesia, where a person can choose to join either their mother's or father's clan depending on land availability." An anthropological study of Polynesian societies.
- "The ambilineal structure allowed families to strategically place children in whichever lineage had the most political influence." Explaining flexible inheritance strategies.
Memory hook
Think of someone who is 'ambidextrous' (using both hands). An 'ambilineal' person can use 'both' lines of the family, choosing the one they want. Ambi- (both) + lineal (lines) = choice of both lines.
When not to use
Do not confuse with bilateral, where both sides are tracked simultaneously without a requirement to choose one line over the other.
Fun facts
- Ambilineal systems are incredibly practical for island ecosystems; if one island becomes overcrowded, families can strategically shift their children's lineage affiliation to relatives on a less crowded island.
