Multilingualism 多语制

Multilingualism is the use of two or more languages, either by an individual speaker or by a community of speakers. Multilingual speakers outnumber monolingual speakers in the world's population. Multilingualism is becoming a social phenomenon governed by the needs of globalization and cultural openness. Owing to the ease of access to information facilitated by the Internet, individuals' exposure to multiple languages is becoming increasingly frequent, thereby promoting a need to acquire additional languages. People who speak several languages are also called polyglots. As far as learning a language, multilingual speakers have acquired and maintained at least one language during childhood, the so-called first language (L1). The first language (sometimes also referred to as the mother tongue) is acquired without formal education, by mechanisms heavily disputed. Children acquiring two languages in this way are called simultaneous bilinguals. Even in the case of simultaneous bilinguals, one language usually dominates over the other. People who know more than one language have been reported to be more adept at language learning compared to monolinguals. Additionally, bilinguals often have important economic benefits over monolingual individuals as bilingual people are able to carry out duties that monolinguals cannot, such as interacting with customers who only speak a minority language.
