Last week, I was in Myanmar. This is the Shwedagon Pagoda in Yangon.
Our guide told us that there is a large ruby at the top, and Myanmar produces the 'most rubies in the [wɔː]'. When she said this, I had an image of the Second World War cutting supplies from everywhere else, but somehow Burma (as it was then called) managed to continue producing them. It took me a while to realise she was saying 'most rubies in the world' – and indeed, Myanmar produces about 90% of the world's rubies (according to the Lonely Planet guide, page 272).
This use of [ɔː] for the NURSE vowel with words starting with 'wor' (as discussed in my previous blog) seems to be very common around the world. I wonder if it will become the standard pronunciation in World Englishes. Maybe it already is the standard, and people like me need to get used to it.
