Usually, there is one dominant and prestigious dialect (e.g., the dialect of the capital city, or a formal hochsprache like High German or Standard Dutch) that gravitates the dialects to itself and absorbes only a few features from the dialects. Note that in any case, dialect levelling is rarely equal to all dialects involved. It is a branch of linguistics and sociology.

To complicate matters: When the creole is influenced by one of the original languages, a process called decreolisation can start which can be described as dialect levelling between the creole and the original language. Ans: ( Short Points: Definition,Code,Dialect,Sociolect,Register,Idiolect,Diglossia,Pidgin,Creole.) Definition Sociolinguistics: Sociolinguistics is the study of the relation between language and society.

When native speakers emerge in a group of pidgin-speaking peers, they develop a creole with typical grammatical features different from the original languages from which the pidgin was formed. A pidgin is not considered a full-fledged language. In contrast, a pidgin discards all the original complex grammatical features. The dialects just converge to each other or to a dachsprache dominating them. The dialects undergoing dialect levelling are full-fledged languages at each time of the process. In the process of dialect levelling, the grammatical system of the dialects (tense, nominal case systems, other complex features) usually stays intact.
