A simplified language derived from two or more languages is
called a pidgin. It is a contact language developed and used by
people who do not share a common language in given 【1】
geographical area. It is used in a limited way and the structure is
very simplistic. Since they serve as a single simplistic purpose,【2】
they usually die out. Furthermore, if the pidgin is used long 【3】
enough, it begins to evolve into a more complex language with a
more complex structure and rich vocabulary. Once the pidgin has 【4】
evolved and has acquired native speakers (the children learn from【5】
the pidgin as their first language), it is then called a Creole. An
example of this is the Creole from Papua New Guinea, Tok
Pisin, which has become a national language.
Reasons for the development of Pidgins
In the nineteenth century, when slaves from Africa were
brought over North America to work on the plantations, they 【6】
were separated from the people of their community and mixed
with people of various other communities, therefore they were
able to communicate with each other. So they couldn't come up 【7】
with a plot to escape back their land. Therefore, in order to 【8】
finally communicate with their peers on the plantations, and with
their bosses, they needed to form. a language which they could 【9】
communicate. Pidgins also arose because of colonization.
Prominence languages such as French., Spanish, Portuguese, 【10】
English, and Dutch were the languages of the colonizers. The
people of the colonies tried to communicate with the colonizers
using a mixed language.
