Etymology
It is inherited from Proto-Hellenic *pəkʰús,[1] inherited from Proto-Indo-European *bʰénǵʰus (“thick”), from the root *bʰenǵʰ- (“thick; to swell”).[1][2] Beekes, who reconstructs it as *bʰn̥ǵʰ-u-, calls it an old u-stem adjective.[3] The Greek form starts from *φαχύς (*phakhús), whose first aspirate was lost by dissimilation before the second.[4][5]
Cognate with Sanskrit बहु (bahú, “much, many”), Avestan 𐬠𐬄𐬰𐬀𐬵 (bązah) and Hittite panku- (“total”).[3][1][4] Chantraine rejects a link with Latin pinguis (“fat”), for both form and meaning.[4]
Earliest recorded meaning
It is found from Homer on, meaning thick or stout: a warrior's strong hand, a thick thigh or neck, a massive stone, and blood that is thick and clotted.[6][7][8]
Semantic evolution
Hesiod uses it of a foot and of tree trunks.[6][7] Of liquids it meant thick or curdled: Herodotus uses it of a juice that runs thick and black, and the Hippocratic writers of marsh water and urine, and they called certain diseases “thick” because they were thought to come from thickened phlegm.[6] In Herodotus and Aristophanes “the thick ones” are the men of substance, the wealthy.[6] Comedy and later prose used it for someone thick-witted and stupid, and a late proverb called a dullard “thicker than mud”.[6] Aristotle applied it to a thick, heavy sound, as opposed to a thin one, and Dionysius of Halicarnassus to a coarse, heavy style.[6]
The adjective lived on through Medieval Greek and is still Modern Greek παχύς (pachýs), thick in dimensions, and fat, of people and animals.[9][10] Science took the form English pachy-, “thick, massive”, from its Latinized form.[11]
