It is expedient that a study in PCS must be precluded with a close look at creole languages. among present day linguists, David de Camp seems to have presented a comprehensive view of creole language in his introduction to "The Study of Pidgin and Creole Language" (In Hymes: 1971; 15-17). The following account is extracted from the section on the characteristics and definitions of creole languages.
Originally, the term creole was derived from Postuguese crioulo. It meant then, a white man of European descent, born and raised in a tropical or semi-tropical colony. Later, this meaning was extended to indigenous natives and others of non-European origin. Later still, the term was applied to certain languages spoken by creoles. From then on, the term was extended to other languages of similar types.
Creoles have been traditionally classed as a deviant dialect of a standard language. It is also often called 'mixed language' which merely suggests that it is only a potpourri with no uniform coherent structure of its own. However, De Camp considers it a genuine language in its own right and not just a macaronic blend or inter-lingual corruption of standard languages.
Most creoles are European-based. They have, therefore, derived most of their vocabularies from one or more European languages. Creole French and Creole English are most frequently traced in West Africa and the New World; whereas, Spanish, Dutch, and Postuguese creoles are found to be more common in other parts of the world.
Further investigations show that by no means is all of the vocabulary of creole shared with its corresponding European language. It has been found, moreover, that in both phonology and syntax, the difference between a creole and a standard language are usually so great as to make them mutually unintelligible. In most cases, a creole is considered inferior to its corresponding standard language, but this is true only in prestige and social status.
A creole is the native language of most of its speakers. As such its vocabulary and syntactic devices like those of any language, are sufficient to meet all the communication needs of its speakers.
