Within Berks County and other adjacent counties of Pennsylvania, the word "Greenwich" is pronounced // GREEN-witch rather than the more common // GREN-itch. This anomaly in pronunciation often leads to confusion with natives of Greenwich, London, New York City, and other areas containing a Greenwich Township, such as Huron County, Ohio.
