Hopefully a_i & kiltpin will tell us how they said it and if they know which language it was from
I learned the word from my mother and she would pronounce it - Eye yah. I believe that it comes from Hindi, which is an oral language only. Because of the lack of being pegged to the written word, it tends to evolve in any direction that it is needed. It is the Pigeon English of the Indian sub-continent.
For example - Go You Shops. Depending on the inflection of the speaker this could either mean "Are you going to the shops?", or "I want you to go to the shops!", or even "Please do me a favour and go to the shops."
