For someone or something (actor -um-; s actor muɴ-) to wear a roof (patient -on) thin by causing dried and rotten grass to come out and fall off, as when someone climbs on it, a chicken scratches it.
Abūlonyu nan manu' an umuy hinan atap di baluy ti yumāhangda ya omod un muntūduh un umudan.
Shoo away the chickens going onto the roof of the house because they will cause (it) to become thin and for sure it will leak when it rains.
