This is intriguing. Why can't we be straightforward and just say 'we don't have horses here'. Instead, we need to say 'there is no our seeing of horse or horse is not of our seeing here'. 

tjapacucunan is so complicated and beautiful! what does it say about Paiwan? I have to know. 

neka a nia rigi imaza. Our horse is not here. This sentence means we have a horse, just the horse is not here but somewhere else. So how can you say horse is not a local species or is introduced in Paiwan?
