A creole language, or simply creole, is a stable form of contact language that develops from the process of different languages simplifying and mixing into a new form (often a pidgin), and then that form expanding and elaborating into a full-fledged language with native speakers, all within a fairly brief period.Millar, Robert M. (2015). Trask's historical linguistics. Routledge. pp. 305-306. While the concept is similar to that of a mixed or hybrid language, creoles are often characterized more narrowly by a tendency to systematize their inherited grammar (e.g., by eliminating irregularities). Like any language, creoles are characterized by a consistent system of grammar, possess large stable vocabularies, and are acquired by children as their native language.Calvet, Louis-Jean. (2006). Toward an Ecology of World Languages. Malden, MA: Polity Press. [173-6] These three features distinguish a creole language from a pidgin.McWhorter, J. H. (2005). Defining creole. Oxford University Press. Creolistics, or creology, is the study of creole languages and, as such, is a subfield of linguistics. Someone who engages in this study is called a creolist.

The precise number of creole languages is not known, particularly as many are poorly attested or documented. About one hundred creole languages have arisen since 1500. These are predominantly based on European languages such as English and French due to the colonization and the Atlantic slave trade that arose at that time.Linguistics, ed. Anne E. Baker, Kees Hengeveld, p. 436 With the improvements in ship-building and navigation, traders had to learn to communicate with people around the world, and the quickest way to do this was to develop a pidgin; in turn, full creole languages developed from these pidgins. In addition to creoles that have European languages as their base, there are, for example, creoles based on Arabic, Chinese, and Malay.

The lexicon of a creole language is largely supplied by the parent languages, particularly that of the most dominant group in the social context of the creole's construction. However, there are often clear phonetic and semantic shifts. On the other hand, the grammar that has evolved often has new or unique features that differ substantially from those of the parent languages.

Overview A creole is believed to arise when a pidgin, developed by adults for use as a second language, becomes the native and primary language of their children – a process known as nativization. The pidgin–creole life cycle was studied by American linguist Robert Hall in the 1960s.

Some linguists, such as Derek Bickerton, posit that creoles share more grammatical similarities with each other than with the languages from which they are phylogenetically derived. However, there is no widely accepted theory that would account for those perceived similarities.; cited in Moreover, no grammatical feature has been shown to be specific to creoles.

Many of the creoles known today arose in the last 500 years, as a result of the worldwide expansion of European maritime power and trade in the Age of Discovery, which led to extensive European colonial empires. Like most non-official and minority languages, creoles have generally been regarded in popular opinion as degenerate variants or dialects of their parent languages. Because of that prejudice, many of the creoles that arose in the European colonies, having been stigmatized, have become extinct. However, political and academic changes in recent decades have improved the status of creoles, both as living languages and as object of linguistic study. Some creoles have even been granted the status of official or semi-official languages of particular territories.

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 in 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 extensively 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.

History Etymology The English term creole comes from French , which is cognate with the Spanish term and Portuguese , all descending from the verb criar ('to breed' or 'to raise'), all coming from Latin .. The specific sense of the term was coined in the 16th and 17th century, during the great expansion in European maritime power and trade that led to the establishment of European colonies in other continents.

The terms and were originally qualifiers used throughout the Spanish and Portuguese colonies to distinguish the members of an ethnic group who were born and raised locally from those who immigrated as adults. They were most commonly applied to nationals of the colonial power, e.g. to distinguish (people born in the colonies from Spanish ancestors) from (those born in the Iberian Peninsula, i.e. Spain). However, in Brazil the term was also used to distinguish between (black people born in Brazil from enslaved African ancestors) and (born in Africa). Over time, the term and its derivatives (Creole, Kréol, Kreyol, Kreyòl, Kriol, Krio, etc.) lost the generic meaning and became the proper name of many distinct ethnic groups that developed locally from immigrant communities. Originally, therefore, the term "creole language" meant the speech of any of those creole peoples.

Geographic distribution As a consequence of colonial European trade patterns, most of the known European-based creole languages arose in coastal areas in the equatorial belt around the world, including the Americas, western Africa, Goa along the west of India, and along Southeast Asia up to Indonesia, Singapore, Macau, Hong Kong, the Philippines, Malaysia, Mauritius, Réunion, Seychelles and Oceania.

Many of those creoles are now extinct, but others still survive in the Caribbean, the north and east coasts of South America (The Guyanas), western Africa, Australia (see Australian Kriol language), the Philippines (see Chavacano), island countries such as Mauritius and Seychelles and in the Indian Ocean.

Atlantic Creole languages are based on European languages with elements from African and possibly Amerindian languages. Indian Ocean Creole languages are based on European languages with elements from Malagasy and possibly other Asian languages. There are, however, creoles like Nubi and Sango that are derived solely from non-European languages.

Social and political status Because of the generally low status of the Creole peoples in the eyes of prior European colonial powers, creole languages have generally been regarded as "degenerate" languages, or at best as rudimentary "dialects" of the politically dominant parent languages. Because of this, the word "creole" was generally used by linguists in opposition to "language", rather than as a qualifier for it.See .

Another factor that may have contributed to the relative neglect of creole languages in linguistics is that they do not fit the 19th-century neogrammarian "tree model" for the evolution of languages, and its postulated regularity of sound changes (these critics including the earliest advocates of the wave model, Johannes Schmidt and Hugo Schuchardt, the forerunners of modern sociolinguistics). This controversy of the late 19th century profoundly shaped modern approaches to the comparative method in historical linguistics and in creolistics.

Because of social, political, and academic changes brought on by decolonization in the second half of the 20th century, creole languages have experienced revivals in the past few decades. They are increasingly being used in print and film, and in many cases, their community prestige has improved dramatically. In fact, some have been standardized, and are used in local schools and universities around the world.Holm (1988, 1989) At the same time, linguists have begun to accept that creole languages are in no way inferior to other languages. The terms "creole" or "creole language" are now used for any language suspected to have undergone creolization, and no longer imply any geographic restrictions nor ethnic prejudices.

There is controversy about the extent to which creolization influenced the evolution of African-American Vernacular English (AAVE). In the American education system, as well as in the past, the use of the word ebonics to refer to AAVE mirrors the historical negative connotation of the word creole.

Classification Historic classification According to their external history, four types of creoles have been distinguished: plantation creoles, fort creoles, maroon creoles, and creolized pidgins. By the very nature of a creole language, the phylogenetic classification of a particular creole usually is a matter of dispute; especially when the pidgin precursor and its parent tongues (which may have been other creoles or pidgins) have disappeared before they could be documented.

Phylogenetic classification traditionally relies on inheritance of the lexicon, especially of "core" terms, and of the grammar structure. However, in creoles, the core lexicon often has mixed origin, and the grammar is largely original. For these reasons, the issue of which language is the parent of a creole – that is, whether a language should be classified as a "French creole", "Portuguese creole" or "English creole", etc. – often has no definitive answer, and can become the topic of long-lasting controversies, where social prejudices and political considerations may interfere with scientific discussion.

Substrate and superstrate The terms substrate and superstrate are often used when two languages interact. However, the meaning of these terms is reasonably well-defined only in second language acquisition or language replacement events, when the native speakers of a certain source language (the substrate) are somehow compelled to abandon it for another target language (the superstrate). The outcome of such an event is that previous speakers of the substrate will use some version of the superstrate, at least in more formal contexts. The substrate may survive as a second language for informal conversation. As demonstrated by the fate of many replaced European languages (such as Etruscan, Breton, and Venetian), the influence of the substrate on the official speech is often limited to pronunciation and a modest number of loanwords. The substrate might even disappear altogether without leaving any trace.
