What about words such as piekarnia, ciastkarnia, suszarnia... is the gen. pl. piekarń or piekarni?
I guess you meant to post this question in that thread: polishforums.com/genitive_plural_female_neuter-18_29589_0.html - genitive (female)
so I'll answer there.
I can never understand why you have got to make a simple subject so complicated and dry.
just for the dumbass you are:
THESE SENTENCES ARE NOT MY EXEMPLES, THEY WERE GIVEN BY THE ORIGINAL POSTER AND I MADE CORRECTIONS WHERE THEY WERE NECESSARY.
I hope you managed to read that despite your blindness.
