Akron Buchtel (Book-Toll)
Not Book-Tell
And also it’s spelled BUCHTEL not Bucthel
Buck-tel is how I've heard it mispronounced a lot.
East Palestine (though the train wreck has gotten their name widely known but the Tine-Teen last syllable was a common error).
Conneaut. I learned from traveling that people really did think it's "Canoe" the water vessel or "Cah-newt". It's Con-EE-Ought.
Pymatuning Valley. This is more my grandmother's generation and others in the area where that Western PA drawl turns it into "pam-a-tune-ing" instead of "Pie-ma-tune-ing". Younger people get it right by that old WPA vocal sound is still common (but dying with phrases like Red-up, etc).
I know some are just butchered because the spelling looks suspect.
Bucyrus, Ashtabula, Cuyahoga, Massillon, Wapakoneta, etc.
If you ever deal with people outside Ohio who aren't from Ohio reference city names in Ohio, you know Massillon is getting butchered. It's always "Mass-ih-lawn" or "Mah-sill-on" or "Mah-sill-in". The emphasis is never right. I don't blame anyone having trouble with Wapakoneta. I did laugh at someone calling it "Ash-tabula" like "Ash-spatula".
