Chauncey, Lancaster, the region is full of pronunciation traps.
Wait, what is the other way to pronounce Lancaster?
LANG-caster vs LAN-caster
The former is close to the Ohio pronunciation; the latter is close to the Pennsylvania way of saying the word. I think the Ohio way is more like LANG-aster. I assume the Pa way is more like the British. I was surprised to find out a few years ago the the local way of pronouncing Portsmouth, Ohio, something like "Porch-muth," is actually the way people in Portsmouth, England, pronounce it, but not like people in the rest of the UK pronounce it. So, I would assume this means some of the first immigrants to Portsmouth, Ohio, were from Portsmouth, England. I'm sure BTC will correct me if I'm wrong here, since he's THE expert on all things Scioto County.
