Vaillant: From earlier *puk-tio- > *pъkť-, related to Russian пук (puk, “bundle”), Polish pąk (“bud”), perhaps Latvian pukuls (“tuft”) (compare *pǫkъ (“bundle, bunch”)).

^* -asъ is the expected Balto-Slavic form but is found only in some Old Czech documents; -axъ is found everywhere else and is formed by analogy with other locative plurals in -xъ.
^** The second form occurs in languages that contract early across /j/ (e.g. Czech), while the first form occurs in languages that do not (e.g. Russian).
