Reconstruction:Proto-Slavic/pyrъ

Etymology
Formally from, (descendants flucturate between mobile /in Lithuanian/ and fixed /in Slavic/ accent paradigms), ultimately from  (according to Witczak, originally ). Cognate with 🇨🇬 (plural refers to the plant), 🇨🇬, 🇨🇬, 🇨🇬.

Synchronically, represents an o-stem variant of i-stems, , with no discernable difference in meaning. Possibly diachronically formed as a (common) objective counterpart to an earlier (neuter) r/n-stem mass noun. Similar constructions are also found in, (whence 🇨🇬, Western-Curonian dial. 🇨🇬).

(The similarity to 🇨🇬, occassionally noted in the literature, is sometimes dismissed as a coincidence in view of its supposed derivation from . However, Róna-Tas et al. reject this and argue that it is indeed related to 🇨🇬. )
