Dear THE WORLD,
It’s pronounced Westminster, NOT WestminIster. There is no ‘i’ there, we’re not making it silent or being pretentious. If you say WestminIster you are wrong, plain and simple. I know there are ministers milling around that general area now and then, but the fact remains.
On the other hand, hearing Americans say Lye-chester Sqaure makes me smile every. damn. time.
