Multilingualism

Multilingualism is the use of more than one language, either by an individual speaker or by a group of speakers. When the languages are just two, it is usually called Bilingualism. It is believed that multilingual speakers outnumber monolingual speakers in the world's population.^[1][2] More than half of all Europeans claim to speak at least one language other than their mother tongue;^[3] but many read and write in one language. Being multilingual is advantageous for people wanting to participate in trade, globalization and cultural openness.^[4] Owing to the ease of access to information facilitated by the Internet, individuals' exposure to multiple languages has become increasingly possible. People who speak several languages are also called polyglots.^[5]

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 usually acquired without formal education, by mechanisms about which scholars disagree.^[6] Children acquiring two languages natively from these early years are called simultaneous bilinguals. It is common for young simultaneous bilinguals to be more proficient in one language than the other.^[7]

People who speak more than one language have been reported to be better at language learning when compared to monolinguals.^[8]

Multilingualism in computing can be considered part of a continuum between internationalization and localization. Due to the status of English in computing, software development nearly always uses it (but not in the case of non-English-based programming languages). Some commercial software is initially available in an English version, and multilingual versions, if any, may be produced as alternative options based on the English original.
