Thank you, Olympian and Jill, but your contributions have nothing to do with the OP.
Rover_KE, you are right. I had thought of mentioning at the top of my post that it does not answer the OP's question, but didn't. Perhaps I should have quoted your post ("
We know that 'thrice' means 'three times', but it's rarely used except in literary or poetic contexts.") while responding instead of OP's. I just wanted to convey that in India using '
double' and '
triple' is quite common and in my mind it was similar to '
twice' or '
thrice', which is also quite common. I make efforts to not limit myself to Indian English, although that is what we hear and read all around us, including on national TV, and I was hoping that bringing this (double/triple) to the notice of the readers of this forum, especially Indian ones, may benefit all from this exchange. So, I hope that what I wrote was not totally out of line. Having said that, please feel free to move or delete my posts as appropriate.
Jill, thank you for explaining why it is confusing, with a real life example. I just knew it is confusing, but I did not realize the reason for it (accent + ambient/background noise). What you wrote also explains why this happens with numbers, and not with letters. I think in the US people do use '
triple A' (as in '
triple-A rating for bonds' or as in 'American Automobile Association'). (Edit: Just saw the Golden Girls clip and it is quite funny. It is quite amazing that you had the exact reference.)
Tdol, thank you for the information regarding use of 'double' and 'two double-two' in BrE.
