The development of a pidgin, which a simplified form of speech that is usually a mixture of two or more languages, is called the pidginization.This is usually a temporary stage in language learning.
The creation of a pidgin usually requires:
Prolonged, regular contact between the different language communities.
A need to communicate between them.
An absence of a widespread, accessible interlanguage.
Also, Keith Whinnom suggests that pidgins need three languages to form, with one (the superstrate) being clearly dominant over the others.
It is often posited that pidgins become Creole languages when a generation whose parents speak pidgin to each other teach it to their children as their first language. Creoles can then replace the existing mix of languages to become the native language of a community (such as Krio in Sierra Leone and Tok Pisin in Papua New Guinea). However, not all pidgins become creole languages; a pidgin may die out before this phase would occur.
Other scholars, such as Salikoko Mufwene, argue that pidgins and creoles arise independently under different circumstances, and that a pidgin need not always precede a creole nor a creole evolve from a pidgin. Pidgins, according to Mufwene, emerged among trade colonies among "users who preserved their native vernaculars for their day-to-day interactions". Creoles, meanwhile, developed in settlement colonies in which speakers of a European language, often indentured servants whose language would be far from the standard in the first place, interacted heavily with non-European slaves, absorbing certain words and features from the slaves' non-European native languages, resulting in a heavily basilectalized version of the original language. These servants and slaves would come to use the creole as an everyday vernacular, rather than merely in situations in which contact with a speaker of the superstrate was necessary.
