Pidgin English
There will be no revelations below. I owe all I have to say to my database and especially to the papers by Ian F. Hancock (1979) and Dingxu Shi (1992). But surprisingly, my folders contain an opinion that even those two most knowledgeable researchers have missed, and I’ll mention it below for what it is worth. Several important dictionaries tell us that pidgin is a “corruption” of Engl. business, and I am not in a position to confirm or question their opinion.
