This (by now not) new idiom with za’u + [adverb] + ne + [sense organ] back from July of last year … we have ftxì, nari, mikyun varified and I guess, ontu for smell is unambiguous but you never specified what the sense organ for ‘feel’ might be: is it ta’leng? Or tsyokx/zekwä?

As for your Na’vi question . . . it’s a good one! Your suggestions about tsyokx, zekwä, ta’leng are all good candidates. I was going to opt for zekwä, since the first example I thought of was where someone feels a piece of cloth—maybe a new shirt or necktie—with their hand and likes the physical sensation of running their fingers along the smooth material. But then I realized you can enjoy the physical sensation of simply wearing a new shirt without your hands touching it . . . it’s just that it feels good on your body. So since our skin is the sense organ for touch, I’d go with ta’leng.
