Bernand Spolsky, in his book Sociolinguistics, describes the factors that make up an individual’s bilingualism. These have to do with the identification of each of the languages involved; the way each language was acquired; skills proficiency level in both languages; internal functions, such as counting or dreaming; external functions, such as carrying out an informal conversation or giving a lecture; and domains. The latest notion is relevant to the concept of bilingualism because a bilingual may have a preferred language according to each of the domains – a location, a set of relationships or a set of topics. According to Spolsky, bilinguals possess a collection of domain-related rules of language choice that enables them to switch the language to signal either a change of role-relation or topic while still being in the same location. This idea of switching between two languages is referred as to code-switching, that is to say, a change by a speaker from one language or language variety to the other, which can take place during a conversation or within sentences depending on the social context. This process of shifting between languages permits linguistic minorities to maintain a sense of identity and a sense of belonging to a larger community. Code-switching may often be a subconscious process as people may not always be aware that they …show more content…

They may usually employ one language at home and the other one may be spoken at school or in the community. In general, all bilingual children grow up to perform in their dominant language , which is the medium of instruction at school. Spolsky mentions that children growing up bilingually not only manage to keep the two languages separate, but they also learn which language to use to which person. In fact, the phenomenon of code-switching demonstrates that every time children alternate between the two languages, they are clearly keeping their languages apart. These children are expected to develop a mixed code for many reasons. One of the main causes has to do with the fact that they may strategically code-switch when they need to fill a linguistic need because they do not know a word in one language, such as “rica food”, or there is no direct translation. They may also switch between languages in order to have stronger bonds with their family or their friends. For instance, a bilingual child who knows English and Spanish may be able to bond with his grandparents
