Overview

Multilingualism describes the ability of an individual or a community to use more than one language for communication. For an individual, the term often means competence in two or more languages; a person who speaks two languages is called bilingual. The phrase "speak more than one language" is commonly used to define the phenomenon in everyday discussion and research: speak more than one language. Multilingual settings can be found within families, workplaces, cities and entire countries.

Characteristics and how it develops

Children exposed to several languages from birth commonly acquire more than one first language without formal instruction, though order and pace of acquisition vary. Other languages are learned later through schooling, migration, work or study. Immigrants often become bilingual as they maintain their home language while learning the language of their new country: see the common experience of immigrants.

  • Code-switching: alternating between languages in a conversation.
  • Diglossia: different languages or varieties used for distinct social functions.
  • Language dominance: one language may be stronger in some domains.

History, distribution and policy

Multilingualism is a global reality: many nations have more than one official language and public services are arranged accordingly. Governments and organizations may hire staff who speak multiple languages to facilitate communication and trade; the rising volume of international trade and travel has increased demand for such skills. Language policy, education choices and migration patterns shape how multilingualism is maintained or lost over generations. Some countries formally recognize more than one official language in legislation and administration.

Uses, importance and examples

Multilingual skills are valuable in diplomacy, commerce, education, healthcare and cultural exchange. In addition to practical advantages, research highlights cognitive and social effects of learning and using multiple languages. People who can use several languages are often called polyglots, and exceptional cases sometimes receive the label hyperpolyglot; notable historical and contemporary figures associated with such skill sets include individuals like Heinrich Schliemann and linguists such as Ghil'ad Zuckermann.

Multilingualism encompasses a spectrum of situations, from balanced bilingualism to passive understanding of several tongues. Communities may practice additive multilingualism, where new languages are added without displacing earlier ones, or subtractive multilingualism, where acquisition of a dominant language leads to loss of another. Educational programs, media in minority languages and community initiatives can support language maintenance. For an accessible introduction to terms and debates, readers may consult general references and policy documents that discuss the social, cognitive and economic dimensions of being able to speak more than one language.

Further reading and resources are often provided by language institutes, migration services and international bodies; for introductory materials and language learning support see institutional pages and community organizations that work on language education and multicultural integration: immigrant services, trade and language, official language resources, and scholarly overviews that treat multilingualism across disciplines.
