What does やあいい exactly mean?


> いったい どんだけ背負やあいいんだか

I'm slightly confused by this やあいい. I can gather from context that he's
essentially "How much one must bear?", basically he's complaining that has to
bear a heavy burden and the word here is likely 背負い

However, what kind of grammar "やあいい" is exactly




背負やあ is a contracted form of 背負えば. `eba` can contract into `ya(a)`. If you
know 見りゃあ is a slangy version of 見れば, it's the same here.

  * [せおう](https://jisho.org/word/%E8%83%8C%E8%B2%A0%E3%81%86): (verb) "to carry on one's back"
  * せおえば se-o- **e-ba** : 仮定形 of 背負う
  * せおや se-o- **ya** : [eba-to-ya contraction](https://japanese.stackexchange.com/a/12525/5010)
  * せおやあ: やあ is a variant of や
