Of course East Texans know how to pronounce Nacogdoches. Spelling it may a little more difficult, but we have the pronunciation down.
What about the Texas town of Mexia? Yes, Muh-Hay-Yuh. That’s an embarassing one to miss! Pronouncing the X makes you look silly.
Ever heard someone from the north go to the flea market in what they say is CAN-Ton? Don’t pronounce the “T” so much peeps. In Texas, we say KANT-n. Ya all!
