Code-mixing As Code-switching
Some linguists use the terms code-mixing and code-switching more or less interchangeably. Especially in formal studies of syntax, morphology, etc., both terms are used to refer to utterances that draw from elements of two or more grammatical systems. These studies are often interested in the alignment of elements from distinct systems, or on constraints that limit switching.
While many linguists have worked to describe the difference between code-switching and borrowing of words or phrases, the term code-mixing may be used to encompass both types of language behavior.
While the term code-switching emphasizes a multilingual speaker's movement from one grammatical system to another, the term code-mixing suggests a hybrid form, drawing from distinct grammars. In other words, code-mixing emphasizes the formal aspects of language structures or linguistic competence, while code-switching emphasizes linguistic performance.
