| Alorese - Adang |
The Alorese and the Adang are in contact since the Alorese settled on the Alor coast, but probably the interaction got more intense after some time, when the Alorese started to trade and exchange women with the Adang, and to make alliances. Today they have many opportunities to meet, as in the city of Kokar, thanks to better road connections and motorbikes, but we believe that the interaction in the knowledge domain is less intense than in the past, because they interact more about practical issues rather than about esoteric knowledge.
