The term for a foreign language used as a common language is
lingua franca
. This refers to a language used for communication between people who don't share a native language. It often arises when a particular language gains prominence due to political, economic, or cultural influence.
Here's a more detailed explanation:
- Lingua Franca:This term originates from a pidgin language used in the Mediterranean area centuries ago, but it now refers to any language serving as a common means of communication across different language groups.
- Examples:English is a prominent example of a modern-day lingua franca, used in international business, science, and diplomacy. Other languages like French, Spanish, and Arabic have also historically served as lingua francas in various regions.
- Vernacular vs. Lingua Franca:
While a vernacular is the native language of a specific place, a lingua franca is used beyond its native speakers for wider communication.
