You needn't have mentioned "eating" - see "cheating" already has "eating" in it

It's actually Dehati English -

Cheating = Chori karke eating....

Better, you could call it an Anglo-Dehati word.

OR, the 'ch' could also have come from a mixture of origins - 'Vinci' - Raul Vinci - I mean...and 'Gandhi' - Papa Gandhi or Mom Gandhi or Son Gandhi...whichever you please...c + h = ch (Beta, Sandhi ke Niyam yaad hain naa ?)...however, in that case it'd be a Latino-Indo-English word... and short for Latino-Indo-English...LIE...

What say you ?
