The story
- Proto-Indo-European · derived from*puḱ-“to press together”
- Ancient Greek · borrowed fromΠνύξ
- English todayPnyx
Borrowed from Ancient Greek Πνύξ (Pnúx); since ancient times it has been claimed the word is derived from πυκνός (puknós, “close-packed; dense; thick”), possibly from Proto-Indo-European *puḱ- (“to press together”), but the Oxford English Dictionary considers this a folk etymology with no evidence supporting it.
