I don't understand the origins of contemporary American African English...I know that there is the dialectologists model the creolists model and the integrated model but i don't get what each one is

Creole is an adaptation of pidgin Engish in which only a few grammatical forms and vocabulary are used. For more information about creole and dialect, check these sites.

The study of the origins of contemporary American African English involves different models that linguists have proposed to understand how this dialect developed. Let's break down each model to gain a better understanding:

1. Dialectologists Model:
The dialectologists model suggests that African American English (AAE) is primarily a variation of Southern American English (SAE). According to this model, AAE emerged through the regional dialectical features of the southern United States, where many African Americans lived during slavery and after emancipation. It emphasizes the influence of the unique linguistic characteristics found in the southern region.

2. Creolists Model:
The creolists model argues that AAE developed from a Creole language that emerged during the time of slavery. Creole languages are formed when people with different native languages come together and must communicate. In the case of AAE, this model suggests that enslaved Africans, who spoke diverse languages, developed a simplified Creole language as a means of communication. Over time, this Creole language gradually transformed into what is now known as AAE.

3. Integrated Model:
The integrated model combines aspects of both the dialectologists and creolists models. It acknowledges the influence of southern dialects on AAE but also recognizes the significant contributions from African languages and grammatical structures. According to this model, AAE evolved as a result of contact between African languages, Creole features, and the local southern dialects spoken by African Americans.

It's important to note that these models offer different perspectives on the origins of AAE, and no single model can fully explain its development. Furthermore, ongoing research in sociolinguistics continues to shed light on the complex factors that have influenced AAE's formation and evolution.
