Reconstruction:Proto-Indo-European/písdeh₂

Etymology
As suggested by Hamp 1968: from + ; i.e. originally an euphemism meaning "what one sits on". Compare <  +.

Archaic formation, but with geographically limited distribution, only to central and eastern Indo-European dialects.

Reconstruction
If the analysis as a compound is correct, the word would start with otherwise unreconstructable initial laryngeal *h₁.

Diphthong in Old Prussian would require PIE, and other Baltic cognates are then according to Hamp later borrowings from Slavic. That explanation is favored by Kortlandt and Dybo, according to whom the operation of Winter's law was blocked in clusters containing.
