1.-Who else would be "nor gehiaho" For example: Nor gehiago etorri nahi du? =who else wants to come? 2- Although = Nahiz eta/arren. But this is more complicated. "Nahiz eta" goes at the beggining of the sentence, and the verb of the first part of the sentence doesn't go conjugated.. For example: Nahiz eta asko jan, argala nago. = Although I eat a lot, I am skinny. Arren goes in the middle of the sentence. For example: Asko jan arren, argala nago. = Alghough I eat a lot, I'm skinny. Even if would be "nahiz eta" aswell. I don't think "all the more so/" has an exact translation but you could say "batez ere", which means especially. I hope this helped you ^^

To get = Conseguir I'll get it = Lo conseguiré Go get it! = ¡Ve a conseguirlo!
