Google Pigeon English: Etymology. Pidgin derives from a Chinese pronunciation of the English word business, and all attestations from the first half of the nineteenth century given in the third edition of the Oxford English Dictionary mean 'business; an action, occupation, or affair' (the earliest being from 1807)
Also, a hybrid of English and local languages, it traces its roots to the Atlantic slave trade in the 17th century. More than 75 million people are believed to speak pidgin across Nigeria, Ghana, Cameroon and Equatorial Guinea.
In the Carribean, this type of speech is known as 'Patwa/Patois', i.e. speech or language that is considered nonstandard, although the term is not formally defined in linguistics. As such, patois can refer to pidgins, creoles, dialects or vernaculars, but not commonly to jargon or slang, which are vocabulary-based forms of cant.
To to answer the comment on 'Did you do it?' becomes 'You do it?' you might get 'I did not do it! becomes 'Me nah do it!' In this instance 'Me' is 'I' and 'nah' is 'not' or 'did not'.
The term patois comes from Old French patois, 'local or regional dialect' (originally meaning 'rough, clumsy or uncultivated speech'), possibly from the verb patoier, 'to treat roughly', from pate, 'paw' or “pas toit” meaning “not roof” (homeless), from Old Low Franconian *patta, 'paw, sole of the foot' -ois.
There is an argument that Carribean slaves were not taught to speak a quality version of the slave master's mother tongue which may have been English, French, Dutch, etc. Teaching evolved from minimal learning requirements for the benefit of following rules. A modern argument for this issue may be seen here: http://jamaica-gleaner.com/gleaner/20110418/letters/letters3.html or http://www.jamaicaobserver.com/opinion/patois-is-not-the-problem-stupid-_150436?profile=1096
To put it into context, in the UK, there was no national system of education before the 19th century. We should all have been speaking in a more basic manner. Only a small section of the child population received any schooling. This was either religion-based or as universities, for those whose families had the considerable resouces required.
The industrial revolution and the need to follow rules made by factory owners lead to a forced requirement for children to, under duress and on pain of financial penalty (for the parent), attend school. Prior to this schooling, or practical skill, was provided by the family
Language is indicative of the philosophy of education during industrialisation as the Industrial Schools Act was passed in 1857 and gave magistrates the power to sentence children between the ages of seven and fourteen years to a period of education in an industrial school (https://clairegarside.com/2020/01/22/the-effect-of-industrialisation-on-education-policy-and-the-school-system/).
