A word that when capitalized changes meaning, and sometimes pronunciation.
For years as a kid, no joke, I couldn’t understand why there was a polish club at the bottom of our road. Yes, it was a Polish club.
Some examples: turkey/Turkey, may/May, march/March, august/August, lent/Lent, reading/Reading, mobile/Mobile, polish/Polish, alpine/Alpine, china/China.
When they change pronunciation they’re also heteronyms.
