1. "WOO-ster" (with a long "oo" sound like "moon")
* This is the most common pronunciation in the US.
2. "WUS-ter" (with a short "u" sound like "but")
* This pronunciation is more common in some parts of the UK, particularly in the Midlands.
It's also worth noting that the name is often associated with the fictional character "Jeeves and Wooster," created by P.G. Wodehouse. In his works, the name is typically pronounced with the long "oo" sound.
Therefore, "WOO-ster" is the safest and most widely accepted pronunciation.
