Comments: Av. par. B (gen. pirí-dul). Cf. also Akhv. Tl., Ratl. piri. The same root with an expressive suffix is present in Av. pír-χ:-ize 'to flash, glitter'. Av. párχ:-ine 'to blaze up' is still another variant of this root (possibly influenced by Lak. parχ 'flash'. Tind. (or Av.) > Khvarsh. (Ram.), Inkh. piri 'lightning'.
