exactly, the plural of pieróg is pierogi. You lose the accent in the plural....
Odd, the website I checked showed the accent. That'll teach me for not relying on Google Translate! :(
I've seen them call them perogies. Damn impossible language...
It's not impossible, it's just a bastardised Polonia word.
Interestingly, Brits don't call them "pierogies", but "pierogi".
