Poking around on the internet today and came across a 2017 paper abstract on the etymology of the word/name επίκουρος. Looks like researcher traces it back to Indo-European. Granted, a little in the weeds but figured I'd share since we have a vested interest in someone named that
I also was watching a video* recently where the person was pronouncing Epicurus/Επίκουρος with stress on the second syllable: -pi- "e-PI-cur-us". Usually, I hear it and pronounce it "e-pi-CUR-us" when Anglicizing it. I had never heard that other pronunciation before and looked back at the original Greek and, sure enough, the acute accent mark (high tone) is on the -pi-/-πι-. That gives a whole different "flavor" to the sound of our founder's name. Give it a try.
Just found these interesting and thought I'd share.
*I'm not advocating the video content just found the pronunciation novel.
