This morning I was giving directions to a colleague and she was most confused when I told her to "take the third exit at the island and then turn left when you get to the outdoor" she didn;t know what an island or an outdoor was.
It appears on discussing this with other colleagues, that these are terms restricted in use to the Midlands and so non-Midlanders would know them as roundabouts and off-licenses. I ahve also since discovered that in parts of Worcestershire, people say dual-track instead of dual-carriageway.
Have you got any good regional words that would not be understood elsewhere? I was amazed that outdoor was one that isn't regularly used as I've said it all my life (obviously!) and had never realised it was a Birmingham word.
