'heel'
ETYMOLOGY
[Perhaps פּיענטע is the older form, from Polish, competing with a newer East Slavic form פּיאַטע.]
Polish pięta; Belarusian пята; Ukrainian п'ята.
{Geller and Gajek, 2023: 55; Herzog 1964: 108}
From Proto-Slavic ✱pętà; from Proto-Balto-Slavic ✱pentà, perhaps from ✱pęti 'to stretch', from PIE ✱(s)penh₁- 'to span, to spin'.

[The strange stratification of nasal and non-nasal variants does not seem to line up with anything. Why?..]
