(2) n. tree.pohon.
Semantic domain: plant
Etymology: PMP *kahiw
'ai aur
• fire wood.kayu api.
'ai jawan
• papaya.papaya.
Note: The second word 'jawan' might be an attribute composed of the noun 'jawa' and the suffix -n. The name 'jawa' historically refers to the island of Java or to a place overseas in general. Thus the name for 'papaya' could originally mean: javanese plant or a plant/tree from overseas. It is unknow to me so far if papaya was imported to Flores or if it is a local plant.
