Reconstruction:Proto-Finnic/porcas
From User talk:Rua
ETY reconstructs the Proto-Indo-Iranian word differently. It also adds that the Erzya and Moksha words might be Finnic loans, and that the less likely theory is it being directly from PIE.
Strombones (talk)
The PIE form is not disputed, as far as I can tell, there's a clear *o in the first syllable. In Proto-Indo-Iranian, *e and *o both become *a, so you get *párćas. If the Uralic terms all preserve the *o, then this would need to be explained in some way.
To be clear, in the new transcription system, it would be Proto-Indo-Iranian *párĉas.
You should have raised the complaint before they were all moved then. See Wiktionary talk:About Proto-Indo-Iranian.
