Which is the term for completely structured language that develops from a blending of native language and introduced languages

Creole is the term for a completely structured language that develops from a blending of native language and introduced languages.

Explanation:

A creole language is defined as a "stable natural language" that develops from the simplifying and mixing of different language within a fairly brief period of time. It is believed that the language had risen when pidgin, which was developed by the adults as a "second language", became the native as well as the primary language of their children. This process of language change and adoption is referred to as nativization.

A creole language is a fully structured language that develops from a blend of two or more languages.
