Historical sources
The Quaquerni are also known by the name Quarquerni, Querquernoi, or Quacernoi. Their ethnonym is registered as Κουακερνοί, by Greek geographer Ptolemy in his Geographies. Scholars see a possible connection with Venetic Quarqueni, as registered by Pliny and located somewhere in historical Istria.Etymology
The name Querquerni is probably related to Latin quercus, which stems from Proto-Indo-European root *pérkʷus, meaning "oak". It is probably a Q-Celtic formation meaning "the Oak People / Warriors", related to:- Middle Irish ceirt "apple-tree", Middle Welsh perth "bush", from *kʷerxt-, from an earlier *kʷerkʷt- < *perkʷt-
- the Continental Celtic toponyms Hercynian forest and the Pannonian tribe Hercuniates, where the early delabialization of kʷ before u prevented p.. kʷ > kʷ.. kʷ: so *perkʷunia > *perkunia > *fercunia; note that there is no u after kʷ in *kʷerkʷern-. They are all related to the Germanic branch maybe borrowed from Pre-Celtic *percunia, that is to say : Gothic fairgunni "mountain ", Anglo-Saxon firgen- "mountain wood", Old High German Fergunna, Virgundia waldus, etc.
- French place names derived from the forms Perciacum, Percoialum, Percunia, Percetum, Erciacum, etc.
