It’s not hard at all. But due to the fact that stealing other people’s words and aggressively mispronouncing them seems to be the official British pastime, I don’t give a fuck how you pronounce it. I’ll pronounce it how it’s spelled, or any other way I damn well please.

There are more of us than there are of you. It’s our language now, you’re an anachronism.

if it’s spelled worchestershire, I’m gonna pronounce it worchestershire.

It’s not a common word for us and the phonetics don’t match the pronunciation whatsoever.

In revenge we invented Arkansas.

Don’t forget the shire.

Meanwhile in Australia: West-eh-share.

I’m from England and wouldn’t pronounce it like this at all. The “woo” sounds like you’re a ghost or something and the “sure” part is just outright wrong.

It’s really hard express through text, but I’d say “wuss-ter-she-er” (the wuss part is pronounced the same way as if you’re refering to a cowardly person), is much closer. Regional accents could make it different tho.
