Concept
Code-switching
Summary
In linguistics, code-switching or language alternation occurs when a speaker alternates between two or more languages, or language varieties, in the context of a single conversation or situation. Code-switching is different from plurilingualism in that plurilingualism refers to the ability of an individual to use multiple languages, while code-switching is the act of using multiple languages together. Multilinguals (speakers of more than one language) sometimes use elements of multiple languages when conversing with each other. Thus, code-switching is the use of more than one linguistic variety in a manner consistent with the syntax and phonology of each variety. Code-switching may happen between sentences, sentence fragments, words, or individual morphemes (in synthetic languages). However, some linguists consider the borrowing of words or morphemes from another language to be different from other types of code-switching. Likewise, code-switching can occur when there is a change in the environment one is speaking. Code-switching can happen in the context of speaking a different language or switching the verbiage to match that of the audience. There are many ways in which code-switching is employed, such as when a speaker is unable to express themselves adequately in a single language or to signal an attitude towards something. Several theories have been developed to explain the reasoning behind code-switching from sociological and linguistic perspectives.
The earliest known use of the term code-switching in print was by Lucy Shepard Freeland in her 1951 book, Language of the Sierra Miwok, referring to the indigenous people of California. In the 1940s and the 1950s, many scholars considered code-switching to be a substandard use of language. Since the 1980s, however, most scholars have come to regard it as a normal, natural product of bilingual and multilingual language use. The term "code-switching" is also used outside the field of linguistics.
