Used to describe hanging up long objects, such as a cloth. For hanging up "round" objects, like a bucket, use tuumill (tetemiill).
Passive form aamillp "is hanging, is hung", with synonym aakwillp (achekwillp). As listed in Barona dictionary, aamill can also mean "is hanging, hung", but aamillp is more specific as the -p is the "passive marker", indicating the action of the verb has been done to the object in question.
