International auxiliary languages

Extracted from the Wikipedia article International auxiliary language.
An international auxiliary language (sometimes acronymized as IAL or contracted as auxlang) is a language meant for communication between people from different nations who do not share a common first language. An auxiliary language is primarily a second language and often a constructed language. The concept is related to but separate from the idea of a lingua franca (or dominant language) that people must use to communicate. The study of international auxiliary languages is interlinguistics.
