From Proto-Balto-Slavic *pínˀtei, from Proto-Indo-European *(s)penh₁-.
Cognate with Lithuanian pìnti, Polish piąć się (“to climb”) and Ancient Greek πένομαι (pénomai, “to toil”) (which apparently got generalized from some domestic work; compare Ancient Greek πήνη (pḗnē, “thread on the bobbin”) > Latin pānus), Proto-Germanic *spinnaną (“to spin”), possibly Old East Slavic понѧва / Russian поня́ва (ponjáva, “blanket”), Old Church Slavonic поукъ (pukŭ) > Russian пук (puk, “bunch, tuft”).
